Abstract:

Riassunto: La villa di Traiano a Centumcellae è un esempio di un lungo dibattito. Anche se la proposta non è nuova, ha un posto centrale nella storia di Civitavecchia sin dalla sua scoperta. Lo scopo di queste note è di fornire una sintesi sulla conoscenza del monumento, indipendentemente dal fatto che la villa di Civitavecchia, nota come Terme Taurine, sia da identificare con la «villa pulcherrima» di proprietà di Traiano e visitata da Plinio. La fase di Traiano è confermata da bolli in laterizio con il nome dell’imperatore (PORTUS TRAIANI), mentre quello di Adriano è rappresentato da un apparato decorativo di marmi pregiati e da latrine individuali come a Villa Adriana.Parole chiave: Traiano, Terme Taurine, Plinio, Centumcellae, Civitavecchia, StatiliusTaurus, Portus Traiani, Ficoncella.

LA DATAZIONE DEI MERCATI DI TRAIANO: UNA VALUTAZIONE ALLA LUCE DI ALCUNI BOLLI LATERIZI INEDITILe recenti proposte di una datazione Domizianea dei Mercati di Traiano vengono prese in esame alla luce di 68 nuovi bolli laterizi ritrovati ai Mercati, alcuni dei quali recuperati anche in contesti pre-Traianei. La conclusione è che tutti i bolli laterizi pre-Traianei si ritrovano insieme a quelli Traianei e quindi non possono essere utilizzati come evidenza per una datazione Domizianea del monumento. Molti dei laterizi con il bollo pre-Traianeo sembrano essere giunti al sito in gruppi, il che sembra suggerire che i laterizi fossero rimasti accumulati per un certo periodo di tempo. Il gran numero di bolli pre-Traianei ritrovati ai Mercati ed in altri edifici Traianei potrebbe essere dovuto all'accumulo di materiale in previsione di progetti Domizianei poi interrotti dopo la morte dell'imperatore. Il problema dell'origine e del tipo di fornitura di laterizi per progetti di vasta scala durante questo periodo viene discusso.

Abstract:

This paper presents the results of investigation conducted to evaluate structural performance of lateritic concrete containing palm kernel shell (PKS) as partial replacement of coarse aggregate by weight. The properties evaluated were: workability, density, compressive strength, microstructure, sorptivity, and water absorption of lateritic concrete with PKS specimens. The coarse aggregate fraction of the lateritic concrete was partially replaced with PKS of up to 50% at interval of 10% by weight. The results showed that: (i) the use of PKS to partially replace the coarse aggregate in lateritic concrete resulted in harsh concrete with low workabilities, (ii) lateritic concrete with PKS as partial replacement of coarse aggregate of up to 50% developed densities that can be used for normal concrete application, (iii) lateritic concrete with PKS as partial replacement of coarse aggregate of up to 10% developed strength that is comparable to the specimens without PKS, (iv) the SEM images of lateritic concrete samples showed a progressively porous internal structure with PKS and (v) lateritic concrete with PKS as partial replacement of coarse aggregate results in porous material but became less porous at longer curing ages. It can be concluded from these results that the replacement of the coarse aggregate constituent with PKS by weight not exceeding 10%, in the production of lateritic concrete, resulted in a material with satisfactory structural performance.

Abstract:

Abstract The subsurface of a proposed site for building development in Mowe, Nigeria, using Standard Penetration Test (SPT), Cone Penetrometer Test (CPT) and Horizontal Electrical Profiling (HEP), was investigated with the aim of evaluating the suitability of the strata for foundation materials. Four SPT and CPT were conducted using 2.5 tonnes hammer. HEP utilizing Wenner array were performed with inter-electrode spacing of 10 – 60 m along four traverses coincident with each of the SPT and CPT. The HEP data were processed using DIPRO software and textural filtering of the resulting resistivity sections was implemented to enable delineation of hidden layers. Sandy lateritic clay, silty lateritic clay, clay, clayey sand and sand horizons were delineated. The SPT “N” value defined very soft to soft sandy lateritic (<4), stiff silty lateritic clay (7 – 12), very stiff silty clay (12 - 15), clayey sand (15-20) and sand (27 – 37). Sandy lateritic clay (5-40 kg/cm2) and silty lateritic clay (25 - 65 kg/cm2) were defined from the CPT response. Sandy lateritic clay (220-750 Ωm), clay (< 50 Ωm) and sand (415-5359 Ωm) were delineated from the resistivity sections with two thin layers of silty lateritic clay and clayey sand defined in the texturally filtered resistivity sections. Incompetent clayey materials that are unsuitable for the foundation of the proposed structure underlain the study area to a depth of about 18m. Deep foundation involving piling through the incompetent shallow layers to the competent sand at 20 m depth was recommended.

Abstract:

Purpose The quest to reduce the cost of concrete which is a major construction input has prompted investigations into assessing the suitability of alternative sources of conventional materials. This paper aims to report the compressive strength and workability of lateritic gravel used as all-in aggregate for concrete production. Design/methodology/approach Three prescribed mixes from all-in aggregate concrete were compared with concrete from lateritic gravel. The paper investigated the variation in strength of four different mixes – 100: 0, 90: 10, 80: 20 and 70: 30 – when portions of the lateritic gravel were replaced with pit sand, respectively, using varying water cement ratios to achieve optimal workability. Findings The density and compressive strength of each cube was measured on the 7th and 28th test dates. An increase in slump and compressive strength was observed in the lateritic concrete, as portions of the lateritic gravel were replaced with sand. However, the rate of increase in the compressive strength tended to decrease with increase in part replacement of lateritic gravel with sand indicating that there was a threshold of percentage of sand increase after which the compressive strengths are likely to decrease. This work never reached this threshold, but it is estimated to be about 40 per cent. Research limitations/implications Investigations focused on lateritic gravel sampled from two sites to represent samples from both the forest and savannah belt. Practical/implications Lateritic gravel can be used as all-in aggregate for non-structural concrete. Originality/value The compressive strengths achieved were better than those for the available normal all-in aggregate used.

Abstract:

In tropical region, in upper layers, soils having red or yellow coloration are generally found and are denominated lateritic soils. They are rich in aluminum hydroxides and ferric hydrates that give an elevated mechanic resistance. When the lateritic soils are used as a construction material in the structural pavement, the exceptional mechanical characteristic reduced the cost over 50% when associated with the sub-base and base layers, or over 25% when the lateritic soil is treated with cement. In São Paulo State, it was made more than ten thousands kilometers of roads where the base or sub-base was made using lateritic soils or lateritic soils treated with cement. In this study, it is showed, through Finite Element Method, a critical analysis of the sub-base and base of airfield pavement using lateritic soils cement base course and Hot-Mix Asphalt thickness surface less than recommended for critical area in according to Federal Aviation Administration (1996). Considering the results, it is possible to propose a reduction of thickness Hot-Mix Asphalt layer, resulting in a reduction of the final cost of implantation of hundreds of airfields in South America.

Abstract:

This paper reports on the flexural strength behaviour of Apa reinforced stabilized lateritic soil beams. The potential of using timber as a reinforcement material is because timber is abundant, cheap and locally available compared to conventional steel. Apa timber possess a tensile strength of 68.34 N/mm2. Experimental and Finite Element Analysis using ANSYS 15 were carried out to determine the flexural strength of Apa reinforced lateritic soil beams. The results showed an increase in the load-bearing capacity with increase in the percentage area of Apa reinforcement used in Lateritic soil beams. BS 8110-1:1997 requires that area of reinforcement for beams should not exceed 4%. At 4 percent area, the flexural strength of the Apa reinforced lateritic soil beams (ALB) was 0.763 N/mm2 with corresponding load capacity of 3.435 kN which is slightly higher than the steel reinforced lateritic soil beams (SLB) of 0.740 N/mm2 with corresponding load capacity of 3.329 kN obtained in the report

Abstract:

Lateritic ore can be heated and deoxidized rapidly via microwave irradiation with activated carbon as deoxidizer. In this paper, we studied the reductive roasting behavior of carbon-containing lateritic ore in microwave field and the composition of products through different heating process with varying carbon content. The results show that the heating process of the lateritic ore is a thermally stable process. The reductive level of lateritic ore can be adjusted by changing the proportion of carbon powders and the heating time of microwave irradiation. During this reductive roasting process, the quality of the added carbon powders will make a great impact on the phase composition of the product and then affect the heating rate. The reductive calcite product mainly consists of magnetite and wastage. With the rising of the content of reducing agent, the reductive level of lateritic ore will increase, which cause Ni and a small quantity of Fe to be deoxidized and forms Ni-Fe alloy.

Abstract:

The objective of this study was to investigate the physical, chemical, and mineralogical composition of lateritic soils in order to use these soils as potential commercial products for industrial application in the future. Five lateritic soils derived from various parent materials in Taiwan, including andesite, diluvium, shale stone, basalt, and Pleistocene deposit, were collected from theBt1level of soil samples. Based on the analyses, the Tungwei soil is an alfisol, whereas other lateritic soils are ultisol. Higher pH value of Tungwei is attributed to the large amounts of Ca2+and Mg2+. Loupi and Pingchen soils would be the older lateritic soils because of the lower active iron ratio. For the iron minerals, the magnetic iron oxides such as major amounts of magnetite and maghemite were found for Tamshui and Tungwei lateritic soils, respectively. Lepidocrocite was only found in Soka soil and intermediate amounts of goethite were detected for Loupi and Pingchen soils. After Mg-saturated and K-saturated processes, major amounts of mixed layer were observed in Loupi and Soka soils, whereas the montmorillonite was only detected in Tungwei soil. The investigation results revealed that the parent materials would play an important role during soil weathering process and physical, chemical, and mineralogy compositions strongly affect the formation of lateritic soils.

Abstract:

Due to the scarcity of well-graded gravel materials, lateritic soils are widely used for road construction in tropic areas. However, lateritic soils often do not meet the strict requirement for subgrade and need to be improved to be used as construction material. Among several approaches used to enhance the engineering properties of lateritic soils, the use of industrial waste materials, such as fly ash, granulated blast furnace slag, is of particular interest to the construction industry as a potential replacement material for Portland cement in soil stabilization. Meanwhile, some effort has been made to study the use of quarry dust in stabilizing lateritic soils. The present work aims at assessing the compaction characteristics of three different types of lateritic soils, treated with quarry dust based geopolymer cement. A systematic study by varying the proportion of geopolymer cement was carried out. Test results show that the soil dry density substantially increased while the corresponding optimal moisture content decreased with the amount of geopolymer cement under varying compactive effort.

Abstract:

The use of Almond leaf-ash for stabilization purposes has not been given consideration. This paper was thus aimed at evaluating the characteristics of almond leaf-ash for the essence of stabilizing lateritic soil. Sourced lateritic soil was divided into 3 components (unmodified soil sample, cement stabilized soil sample and almond leaf-ash cement stabilized soil sample). Almond leaves were calcined at 250°C and subjected to granulation process. Preliminary tests such as; sieve analysis, Atterberg’s limit and specific gravity tests were done on the unmodified soil sample for the purpose of classification. CBR tests were performed on the cement stabilized soil sample and on the almond leaf-ash cement stabilized lateritic soil sample. A model was developed using the Scheffe’s simplex theory with the cement component fixed at 10% of the dry lateritic soil. Results revealed that the soil was observed to be a Silty Clay soil (A-4) with Plasticity index of 9.24%, therefore requiring stabilization. CBR results for the developed trial mixes were greater than the 15.20% obtained for 10% cement stabilization showing that Almond leaf-ash significantly improved the CBR of the cement stabilized lateritic soil. The CBR model developed for the Almond leaf-ash cement soil also proved adequate from the verification test conducted using χ2 statistics. Keywords: Almond Leaf Ash, stabilization, California Bearing Ratio, Scheffe’s theory, lateritic soil.

Results of the hydrogeochemical study of bauxite-bearing lateritic mantles of the Futa Djallon-Mandingo Province, West Africa, have allowed us to first characterize the pore water of vadose and infiltration hydrogeological zone. Abundances of major components (aluminum and iron) of the water are shown to be few orders higher than are those typical of the other waters of lateritic mantles. The pore water is proved to be a major factor of matter redistribution over any bauxite-bearing lateritic profile.

Abstract:

Degradation of lateritic environment as found in the south western and eastern Birbhum district can be considered as irresistible. Inherently poor physical and chemical status of existing lateritic soil profile and radical conversion of land uses as observed at cadastral level are the key factors of land degradation. Lateritic soilscapes are mostly affected by water erosion induced, vegetal and anthropogenic degradation attaining severe and very severe degradation status. Degraded lands in sample mouzas like Ballabhpur, Shyambati, Chawpahari Jungle, Bodakuri and Pachami account for 60.33%, 71.42%, 72.99%, 87.31% and 79.66% respectively out of their total lateritic exposures. In other words about 36.98%, 71.42%, 61.73%, 56.70% and 76.02% out of their total village areas and mostly non agricultural land use are affected by it. Four degraded villages get the higher priority for friendly landscape conservation actions.

Input and output dynamics of petrogenic components was calculated on the isovolumetric base and the obtained data were used to interpret the zoned structure of weathered profile as resulting from its hydrogeological and gas regimes. Although Al separates from Fe in the formation of bauxite horizon, three-valence iron is a typomorphic element of the lateritic landscape as a whole, with 50% Al leaching from lateritic mantle.

Abstract:

This paper compared the initial surface absorption of conventional concrete and laterized concrete containing Portland cement (PC) and sawdust ash (SDA). Laterized concrete was produced at laterite contents of 15 and 30% as partial replacement for sand and SDA contents of 10 and 20% as partial replacement for PC. Compressive strengths at 28 days and initial surface absorption after 10 minutes (ISA-10) at 28, 60 and 90 days were determined at the water/cement ratios of 0.35, 0.50 and 0.65 and assessed at equal 28-day strengths of 25-35 N/mm2. At equal water/cement ratios, compressive strength reduced and ISA-10 increased with increasing content of laterite and SDA. On the other hand, compressive strength and resistance to surface absorption of the blended cement laterized concretes increased with increasing curing age. At equal strengths, all the blended cement laterized concretes have better resistance to surface absorption than the conventional PC concrete.

Abstract:

This study investigates the disposal of lateritic soil available in the state of Maranhao, Brazil, to be used as a natural precursor of alkaline activated material. Lateritic soils are formed in the tropics through weathering processes that favour the formation of iron, aluminium and may contain a large amount of quartz and kaolinite. The quality of laterite for this application may vary significantly depending on both geographic location and depth of a quarry. The identification of quarry locals was carried out in this work, together with a disposal volume estimation considering economic issues about exploration techniques. A comparison of the chemical composition of the lateritic soil of the state of Maranhao with those related in the literature is used to outline the feasibility of using this natural material as precursor of alkaline activated cements. It is concluded that the lateritic soil availability, as well as their characteristics, can enable the development of alkaline activated materials as a future local building material and environmentally friendly.

Abstract:

Indonesia has several Titanium deposit types: beach placer, alluvial and lateritic types. The source of Titanium minerals in beach placer is derived from Tertiary Volcanic Rocks.Theoccurence of alluvial Titanium deposit is closely associated with cassiterite (tin minerals) alluvial in Bangka-Belitung Islands. The source of Titanium minerals (ilmenite) are derived fromweathering on tin mineralization hosted in metamorphic and granitic rocks within uplifted morphology areas. Lateritic Titanium deposits are formed by lateritization process in association with bauxite and nickel in Riau, Kalimantan and Sulawesi Islands. The sources of Titanium are in granitic and metamorphic basement rocks.Java beach placer resources are quite big in tonnage, nearly 50 million tons in total, with significant TiO contents ranging from 8.91 % to 3.17 %. Beach placer along the south shoreline of Java seems to indicate consistency in their mineralogical and genetic types with relativelyhomogenous in TiO contents. Sumatra shows significant resources for lateritic Titanium deposit that is up to 107,800,859 tons with 0.5% to 15 % TiO . The quite interesting resources are indicated by very significant TiO average (15%) with the total of 19,243,757 tons of lateritic deposit type in Bintan Island, Riau,Sumatra. The total resources of beach placer type deposits in Sumatra are much lower than lateritic ones.Sulawesi has both beach placer and lateritic types where the interesting resources of this island are indicated by quite big resources and significant values in TiO grades in North Sulawesi; the tonnage is up to 31,400,000 tons with TiO content average is 9.85 %. On the basis of resources and processing technologies, beach placer deposits in Sumatera, Java and Sulawesi are thought to have potentially economic significance. However, such available resources are needed to upgrade by performing detailed and systematic exploration.Government policies and environment concerns are important aspects for consideration in Titanium commodity development of this country.

Abstract:

Lateritic soils are very abundant in the region of the Federal District of Brazil. If this material could be used in low-volume roads, it would be possible to avoid some environmental problems. Alternative techniques were developed for the use of nonconventional materials as subbase and base layers of flexible pavements. To analyze the technical and economical viability of using local soils, two experimental highways were constructed. Each highway was divided into three sections with different materials in the subbase and base layers, such as fine lateritic soil, fine lateritic soil stabilized with lime, and a mixture of fine lateritic soil and crushed rock. The compaction characteristics were evaluated in laboratory tests. From the time the segments were constructed (in 1998 and 2000) until 2001, the stress–strain behavior of the paving structures was evaluated by in situ tests, such as the plate-bearing, Benkelman beam, and falling weight deflectometer tests. From the results, conclusions were drawn about which of the chosen materials showed the best performance in mechanical behavior.

Abstract:

Lateritic soil is a kind of residual soil that is widely distributed in Asia. The water table of the soil is normally very deep so the upper part of the soil is often unsaturated. The largest lateritic soil area in Taiwan is the Linkou terrace. Because the soil here is loosely cohered and consolidated, the problem of slope instability and landslides has always been a major concern. To evaluate the triggering mechanism of landslides, it is necessary to obtain the failure criterion that represents both the saturated and unsaturated conditions of the soil before any analysis is carried out. The parameter required to define such a failure criterion is the rate of shear strength increase, tan φb, which can be obtained via a series of laboratory strength tests in a modified triaxial system under various matric suction levels. Both the intact and remolded lateritic soils taken from Linkou terrace have been tested for this purpose. The results confirm that matric suction in the lateritic soil contributes significantly to the soil shear strength and that intact soil has a higher strength than remolded soil.

Abstract:

This paper presents the relationship between the dynamic cone penetration (DCP) test results and the unconfined compressive strength of lateritic cemented soils. A series of DCP tests and unconfined compressive strength was performed on lateritic cemented soil. The soils sample used in this study was lateritic soil. The test results for the DCP tests are presented in terms of penetration index. It can be observed that the penetration index decreased with increasing curing period and cement content. Moreover, the unconfined compressive strength of cemented soils increased with curing period and cement content. The relationship between unconfined compressive strength and penetration index is presented. A unique relationship for unconfined compressive strength can be obtained.

A novel isolated strain Acidithiobacillus ferrooxidans BMSNITK17 has been investigated for its bioleaching potential from lateritic soil and the results are presented. System conditions like pH, feed mineral particle size, pulp density, temperature, rotor speed influences bioleaching potential of Acidithiobcillus ferrooxidans BMSNITK17 in leaching out iron from laterite soil. Effect of sulfate addition on bioleaching efficiency is studied. The bioleached laterite iron (BLFe’s) on evaluation for its catalytic role in Fenton’s oxidation for the degradation of ametryn and dicamba exhibits 94.24% of ametryn degradation and 92.45% of dicamba degradation efficiency. Fenton’s oxidation performed well with the acidic pH 3. The study confirms the role of Acidithiobacillus ferrooxidans in leaching iron from lateritic ore and the usage of bioleached lateritic iron as catalyst in the Fenton’s Oxidation.

Abstract:

This paper presents the results of the laboratory evaluation of the characteristics of lateritic soil stabilized reclaimed asphalt pavements (RAP), using 0 – 2% cement, subjected to British Standard Light (BSL) compactive effort to determine their index, compaction and california bearing ratio (CBR) results. The result of the laboratory tests show that the properties of RAP improved when stabilized with lateritic soil, using up to 2% cement. The particle size distribution improved from poorly graded sandy GRAVELLY material for 100% lateritic soil and very sandy GRAVELLY material, to the gradation described as well graded very sandy GRAVELLY material for lateritic soil stabilized RAP, using up to 2% cement. The CBR results obtained from the study show that using the Nigerian General Specifications, 180% CBR value criterion, the maximum CBR of 55% (soaked) for the mix proportion; 40% Laterite + 58% RAP + 2% Cement for A-2-7(2) soil prescribed by the latter is not adequate for stabilization of base coarse. However, judging by the 24-hour strength gain from 17.9 (unsoaked) to 55% (soaked) CBR values, the material can be used as subgrade and subbase materials.

Abstract:

ABSTRACTIndonesia is a tropical country that has very high rainfall rate in the whole year. This is very difficult to overcome with land problems that exist in Indonesia. The condition of the land which has a very not stable soil or we can say that it has collapsible status. Land that has collapse problems is prone to landslides, which involves very low soil carrying capacity and also very high water content in the soil. Many methods can be used to reduce collapsible soi lrate. In this re-analysis we calculate the problem of soil using the lateritic compacted soil columns. This process uses the formation of soil columns by compressing a number of points with a certain diameter so that the carrying capacity of the soil in order to repair and improve minimum occurrence of collapsible soil. But this method has advantages and disadvantages. From the results of the re-analysis conducted it was proven that the stability method using Compacted Lateritic Soil Colums reduced the possibility of soil experiencing collapsible soil. The analysis shows that the value of the edge of displacement or the total decreases due to the stability used using Compacted Lateritic Soil Colums. ABSTRAK Indonesia adalah negara tropis yang memiliki curah hujan yang sangat tinggi. Hal tersebut sangat berpengaruh dengan keadaan stabilitas tanah yang berada di Indonesia. Keadaan tanah yang memiliki stabilitas yang sangat tidak stabil dapat juga di sebut tanah dengan keadaan status collapsible . Tanah yang memiliki keadaan collapsible memiliki rentan mengalami longsor ., di akibatkan daya dukung tanah yang sangat rendah dan juga kadar air yang sangat tinggi di dalam kandungan tanah. Banyak metode stabilitas yang dapat dilakukan untuk mengurangi kemungkinan terjadinya collapsible soil. Pada analisis ulang perhitunga ini membahas stabilitas tanah menggunakanan Compacted Lateritic Soil Colums.Proses stabilitas ini menggunakan cara pebentukan kolom tanah dengan memadatkan bebarapa titik dengan diameter tertentu agar daya dukung tanah mengalami peningkatan dan mencegah terjadinya collapsible soil. Tetapi metode ini memiliki kelebihan dan juga kekurangan. Dari hasil analisi ulang yang dilakukan terbukti bahwa metode stabilitas menggunakan Compacted Lateritic Soil Colums mengurangi kemungkinan terjadinya tanah mengalami Collapsible soil. Dalam Analisis terlihat nilai edge of displacement atau total penurunan yang terjadi berkurang diakibatkan stabilitas yang di gunakan menggunakan Compacted Lateritic Soil Colums.

Abstract:

ABSTRACT: Relatively small aluminous lateritic deposits are abundant in the northeast and northwest parts of the Pará and Maranhão states, respectively. Most of them hosts aluminum phosphate mineralization forming hills and plateaus that stand out in the topography of the undulating plains of this region. The Piriá ridge is one of those topographic features, covered by lateritic iron crusts that have been studied in the 1970s as part of iron ore exploration campaigns and recently for phosphates prospection. This study improves the knowledge about the evolution of the lateritic Piriá deposit and demonstrates its relationship with the most evolved laterites of the Amazon, known as mature laterites, which formed major ore deposits during the Paleogene. Samples of a 17 meter-deep borehole were investigated through mineralogical (X-ray diffraction -XRD, optical and electron microscopy) and chemical methods (inductively coupled plasma mass spectrometry - ICP-MS, inductively coupled plasma optical emission spectrometry - ICP-OES and X-ray fluorescence - XRF). The studied lateritic profile comprises a clay bauxitic horizon overlaid by an aluminous iron crust. Upwardly continuous dissolution of kaolinite occurs with the formation of gibbsite, as the result of intensive leaching, resulting in a higher Al2O3 content in the crust. The continuous formation of hematite from goethite resulted from the transition to more arid conditions. Anatase is a newly formed mineral (100-400 nm crystallites), showing a gradual increase, following the increase in TiO2 content, which is high and indicative of a mafic parent rock, confirmed by the Ti × Zr dispersion pattern. Prominent zoning in the lateritic profile is characterized by the mineralization in bauxite and augelite and abrupt chemical transition between the horizons, marked by a decrease in Si and increase in Fe content from the bottom to the top of the profile. These features are compatible and indicative of mature laterites formed in Amazon during the Paleogene.

Abstract:

Hydraulic characteristic of the exposed ground plays an important role in the construction of “sponge city,” which is a popular concept in the world recently. Loess soil, which is a common geomaterial in its distribution area approximately 9.3% of the world’s land surface, usually could not satisfy the engineering requirement only by compacting without any other treatments. This paper aims to investigate the effect of a natural geomaterial, lateritic soil, which is more economical and environmental than the traditional admixtures such as cement and lime, on the saturated hydraulic conductivity (ksat) of compacted loess. A series of falling-head permeability tests on pure loess and lime-treated loess were carried out firstly for comparison; then lime-treated loess mixed with different contents of lateritic soil was tested. To verify the availability of the coverage of high density lateritic soil on pure loess for antipermeability, which is a common treatment in local area, tests of different thickness of the coverage were conducted. The test results revealed that the admixture of lime could obviously decrease ksat of pure loess and 3% might be the most economical content. An empirical algorithm was proposed based on the results to estimate ksat of lime-treated loess of which the lime content is out of the scope studied in this paper, and it would be useful for engineering design and numerical simulation of safety evaluation. The addition of lateritic soil in the 3% lime-treated loess could further decrease ksat and its performance for antipermeability was better than increasing the lime contents simply. The coverage of high density lateritic soil could also improve the antipermeability of loess, and thickness at least of 30 mm was suggested for engineering practice.

Abstract:

A first-order reliability method (FORM)was employed to assess the compaction water content, CWC (i.e optimum moisture content) of residual lateritic soil mixed with plantain peel ash (PPA) and compacted with British Standard Light (BSL)and British Standard Heavy (BSH)energies, for flexible pavement applications. A Multi-linear regression model was generated from values obtained via laboratory tests using Mini-tab R15 software, which served as a performance function that was applied for the analysis. Using the regression models for CWC, established distributions for the relevant soil factors, safety index (SI) was computed using CWC as a dependent factor and the soil factors Plantain Peel Ash (PPA); Plasticity Index (PI); Percentage File (PF); Specific Gravity (Gs) and Compactive Effort (CE)as self-determining factors). The results revealed that the safety index is sensitive to changeability in the soil factors. Outcome from the analysis show that Gs and CE are greatly affected by alteration in the coefficient of variation (COV), and so it is essential to control Gs and CE in lateritic soil–PPA mixes in road pavements. From the safety index values it reveals that PPA content has a minimal consequence as its value virtually remained constant at all COV used. Stochastically, lateritic soil mixed with PPA produces an acceptable safety index value of 1.0, as mentioned by the Nordic Committee on Building Regulation (NCBR) at 10% COV for BSH of compaction water content only. Therefore a more effective additive such as cement, lime, or bitumen is recommended for modeling CWC of lateritic soil-PPA mixes for road pavement at 10–100% series of COV.

In questo articolo sono esposti i primi risultati dell’indagine condotta sulle tecniche e i materiali da costruzione dell’isolato adrianeo nel tratto occidentale della Nova Via, costruito insieme all’ampliamento dell’angolo NordOvest della Domus. In particolare, l’analisi metrologica dei laterizi ha chiarito come gli approvvigionamenti di bipedali, sesquipedali, bessali, tegole fratte e laterizi di reimpiego venissero redistribuiti all’interno dell’edificio. La ripartizione delle tecniche edilizie nelle diverse porzioni murarie obbediva, infatti, a una razionale logica economica e strutturale.

Abstract:

Lateritic deposits contain oxide ores and usually consist of three layers, namely the limonitic, the saprolite and the garnieritic layer. Limonite, which comprises the top lateritic layer, is a homogeneous ore consisting mainly of goethite with which nickel is associated. Microbe-mineral interactions are of interest for biogeochemical cycles. Microorganisms which are able to mediate redox transformation of Fe-oxide containing minerals are of particular interest when effective bioremediation strategies for insoluble hydroxide and oxide minerals are designed. Quantitive real-time polymerase chain reaction (qPCR) is a culture independent method which is used for the quantification of environmental microorganisms. The aim of this work was to enumerate the microorganisms in different lateritic deposits at Moa mine (Holguin, Cuba) by qPCR and also to obtain Fe (III)-reducing enrichment cultures. A higher microbial abundance was detected in the sampling sites 5124 and 5125 and a lower one in the site 5121. Both, Archaea and Bacteria occurred in all samples except for site 5121 where Bacteria were not detected by qPCR. The Geobacteraceae which comprise Fe-(III)-reducing bacteria were detected at all five lateritic ore sites. The results indicate that these bacteria play a role fundamental in the formation of sediments with a number of oxidized or partially oxidized iron compounds such as magnetite, hematite, goethite and various Fe (III)-oxyhydroxides.

Abstract:

The lateritic soils collected from a tea garden were used to explore the regeneration process using different O2 contents for high-temperature desulfurization. The desulfurization and regeneration experiments were carried out using a fixed-bed reactor at 500°C and the gaseous mixture composed of 1% H2S, 25% CO, 15% H2, and balance N2 for the desulfurization process. Experimental results showed that the regenerability is better when the air was used as a regeneration gas and the regeneration time is shortened. Multiple regeneration experiments indicated that lateritic soils can be regenerated by passing air and can thus be reused many times and its regeneration efficiency is slightly better than that regenerated by 1% O2. The sulfur capacity after air desulfurization/regeneration cycles was examined by elemental analysis with a value ranging from 1.40% to 1.49%, and residual sulfur was detected with a value of 0.12% after the diluted 1% O2 regeneration. No sulfur was detected for the regenerated lateritic soil after air regeneration. From NMR structural identification, the 6-coordinated octahedral structure of Al and trioctahedral coordinated Si are the major Al-containing and Si-containing compounds. Broad shoulder peaks were detected after regeneration process that may be associated with the formation of aluminosilicate and further reduces the dispersion of iron on the surface of lateritic soils.

This research was conducted to understand the characteristics of lateritic steel through hot forging process by the mechanical and microstructure behaviour. The research methodology was chained by variety of preheating temperature of 800; 1000; 1200 °C and forging force from 0 until 1000 kilonewton. In case of hot forging values was obtained the impact and hardness properties also microstructure that compared with as-cast steels. The results of impact strength increased by 81.83% at the temperature of 1200 °C and the hardness increased by 4.99% at 1000 °C, for the microstructure analysis was produced the ferrite and pearlite phases with the fine grains. The chemical composition of steel is classified in low carbon steel included in lateritic steel it contains low alloy 1.78 Ni and 0.553 Cr %wt.

Abstract:

AbstractA silver-palladium alloy with structural formula close to AgPd has been found in laterite from the Bahia lateritic gold deposit. The alloy occurs in a void of an iron oxide nodule, associated with goethite and hematite. The angular shape and protuberances of the alloy grains suggest crystal growth in a lateritic environment, indicating that the alloy is a secondary mineral precipitated during lateritisation. The oxidation of sulphides of the parent rocks probably favoured the migration of palladium and silver as transient thiosulphate and sulphite complexes. Destruction of the thiosulphate and sulphite ligands could result in precipitation of both palladium and silver as an alloy. Eh-pH phase diagrams for Pd-H2O-C1 and Ag-H2O-C1 systems show that both palladium and silver are stable in lateritic environments under lower redox potentials. Such an environment may exist at the top of the ferruginous zone due to the abundant organic matter near the surface.

Physico-chemical properties and the environmental impacts were studied relative to the leaching of rubber fly ash and bottom ash. The pozzolanic properties of fly ash and bottom ash were confirmed by the chemical composition, including silicon oxides, calcium oxides, and aluminum oxides. The geo-technical characteristics of rubber wood fly ash and bottom ash, i.e., modified compaction, plasticity, and the soaked California Bearing Ratio, were evaluated to assess the feasibility of fly ash or bottom ash mixed with lateritic soil as aggregate materials for the subbase in road construction in order to optimize the replacement of lateritic soil by fly ash or bottom ash. The leachates from rubber fly ash and bottom ash did not exceed standard thresholds. The measured characteristics of fly ash or bottom ash mixed with lateritic soil were in good alignment with the effective engineering thresholds. Recommendations were developed for safe reuse of byproducts from rubber renewable power plant in subbase road construction.

Abstract:

This study presents the experimental investigation carried out on the compressive strength and water absorption properties of lateritic blocks stabilized with cement and locust bean pod extract. Tests were carried out in which different sample batches of cement blocks (0.1, 0.2, 0.3, 0.4 and 0.5kg) were moulded and different sample batches of locust bean pod extract blocks (50, 100, 133, 150 and 200g/litre) were moulded and with both cement and locust bean pod moulded too. The compressive strength of the lateritic block samples were tested at 28 days. The results indicated that the cement with locust bean pod extract significantly increase the compressive strength of the lateritic block samples. This compressive strength increases as the amount of cement and locust bean pod extract was increased. This is a validation of the high possibilities of both cement locust bean pod extract being utilized as a binder in the production of blocks for low housing construction in developing areas of Nigeria.
