Abstract:
The review paper focuses on utilizing various sea shell ashes, including cockle, clam, oyster, mollusc, periwinkle, snail, and green mussel shell ash, as partial replacements for cement. It aims to promote environmental sustainability and mitigate the issues associated with global warming. Cement production is known to have significant environmental impacts across all stages, including air pollution through dust and gases, as well as noise and vibration during quarrying and milling processes. One proposed solution is the adoption of modified cement, which refers to cementitious materials designed to match or surpass the performance of Portland cement while incorporating recycled and waste materials, thereby reducing the demand for raw materials and promoting sustainability in construction. Utilizing sea shell ash as a partial replacement for cement in concrete has the potential to yield substantial energy savings and offer significant environmental advantages. Previous investigations have explored the chemical and mechanical properties of concrete produced with sea shell ash replacements, including specific gravity, chemical composition, compressive strength, tensile strength, and flexural strength. The results indicate that the optimal replacement percentage for sea shell ash in cement lies within the range of 4–5%.

Abstract:
Concrete is the most extensively used construction material in the world. Among the constituents of concrete (cement, coarse aggregate, fine aggregate) cement is the most expensive one. The production process of cement leads to generation of CO2. It is estimated that nearly 8% of global CO2 is generated during the production of cement. The objective of this study is to find the suitable replaceable material instead of cement. In this study biochar is used as a material for partially replace the cement. Biochar is a type of charcoal produced from biomass through a process called pyrolysis which involves burning of organic material in absence or limited supply of oxygen. Cement is replaced with biochar at 1%, 3%, 5%, 7%, 9%, 11%, and 13% by the weight of the cement. Slump tests as well as compressive strength test are performed on fresh and hardened concrete after curing period of 7 and 28 days. The results are then compared with conventional concrete (at 0% replacement) to determine the best combination of replacement of the material. From the investigation it was observed that 5% of biochar is best suitable for replacement of cement in concrete mix.

Abstract:
Abstract Cement production significantly contributes to greenhouse gas emissions, specifically carbon dioxide (CO2). In addition to the CO2 emissions from cement production, the increase in palm oil fuel ash (POFA), which is the by-product of the palm oil industry, can also contribute to environmental pollution. This study carried out on POFA and metakaolin (MK) as a partial cement replacement can reduce the problem of greenhouse and environmental effects. Apart from that, it can also increase the level of concrete strength. The slump and compressive strength tests were carried out first on concrete that uses fine metakaolin (FMK) only as a partial cement replacement to obtain an optimum value of FMK. Thus, the optimum FMK content found in this study was 20%. Next, slump tests, compressive strength tests, and heat of hydration tests were carried out on samples containing FMK and POFA content as a partial cement replacement up to 40% of the total cement replacement. The POFA content starts at 5%, followed by 10%, 15%, and 20%. In addition to that, FMK content of 20% and superplasticizer (SP) of 2% were constant for all design mixes. The workability of concrete decreases with the inclusion of FMK and POFA as partial cement replacements and 2% of SP as a constant. However, the strength of concrete containing 20% FMK and 5% POFA as partial cement replacement has given better compressive strength than ordinary Portland cement (OPC) concrete up to 14.07% at 28 days. Additionally, it is found that the exact amount of 20% FMK and 5% POFA enables concrete to be reduced to 5.54% in peak temperature compared to OPC concrete. Furthermore, the formation of C-S-H gel was increasingly generated and able to fill in the gaps in concrete when the POFA content increased, thus making the concrete denser and stronger than the control series.

Abstract:
The work in this thesis examines the suitability of utilising ground waste brick as a cement replacement material. The brick types investigated were obtained from the UK,Denmark, Lithuania and Poland. Cement was partially replaced by various quantities and types of ground brick in mortar and concrete. Compressive strength, pore size distribution and sorptivity of mortar generally all benefit from the presence of ground brick and the greatest effect can be seen after water curing for one year. Compressive strength of concrete is also shown to increase as the fineness of ground brick increases although the optimum particle size for ground brick in concrete is still to be determined. The ground bricks investigated have a significant effect on the performance of ground brick mortar when exposed to sodium sulphate solution and synthetic seawater. It is seen that depending on the chemical and phase composition, the effect of ground brick can increase substantially the rate of deterioration of mortar or can reduce significantly the expansion observed. No definite mechanism was identified as being responsible for the observed deterioration of mortar exposed to sodium sulphate solution although it seems likely that water intake due to ettringite formation and adsorption of water by the resultant colloidal product are the primary causes of expansion. Sulphate content, glass content and oxide chemistry of brick are key factors as to its performance when used as a cement replacement material in mortar. Bricks with a high proportion of low calcium glass make very effective pozzolans. Bricks with high calcium glass or a low proportion of glass should not be used as pozzolans. Small amounts of sulphate in ground brick do not have any serious deleterious effects on ground brick mortars and can be beneficial. It is established that it is technically feasible to partially replace cement with ground brick in mortar and concrete, depending on its chemical and phase composition to produce a more durable, cost effective and (due to the lower cement content) a less environmentally damaging material than that produced without cement replacement.

Abstract:
Utilization of fly ash as a supplementary cementitious material adds sustainability to concrete by reducing the green house gas emission associated with cement production. Fly ash is a by-product of coal fired power stations. The properties of fly ash depend on the type of coal and its burning process. Due to the variation in composition, different fly ash affects the properties of concrete differently. Research data on the performance of concrete containing the Western Australian fly ash is scarce in literature. In this study, mechanical and durability properties of high strength concrete using Class F fly ash from Western Australia were investigated. The ACI 211.4R-08 guidelines were followed to design two series of concretes, each having one control concrete and two fly ash concretes using 30% and 40% fly ash as cement replacement. Fly ash concretes of series A were designed by adjusting the water to binder (w/b) ratio and total binder content to achieve the same strength grade of control concrete. In series B, w/b ratio and total binder content were kept constant in all the three mixtures. Samples were water cured for 7 and 28 days; and were tested at different ages. The mechanical properties were tested by compressive strength, tensile strength and flexural strength test. The investigated durability properties were drying shrinkage, volume of permeable voids, water and air permeability, carbonation and chloride ion penetrability.The 28-day compressive strength of the concrete mixtures varied from 65 to 85 MPa. The fly ash concretes showed lower drying shrinkage than control concrete when designed with adjusted w/b ratio and the total binder content. Inclusion of fly ash reduced sorptivity and water permeability significantly at 28 days. Fly ash showed no adverse affect on air permeability of concrete. Fly ash concretes showed similar carbonation and had less chloride ion penetration as compared to the similar grade control concrete. In general, incorporation of fly ash as partial replacement of cement improved the durability properties of concrete at early age when w/b ratio was adjusted to achieve similar 28-day strength of the control concrete. The durability properties improved with the increase of fly ash content from 30% to 40% of the binder and with the increase of age. Fly ash concretes of series A achieved similar service life of control concrete in carbonation and resulted in higher service life than that of the control concrete, when chloride diffusion was considered as the dominant form of attack.

Abstract:
Concrete is an integral material in modern infrastructural requirements worldwide. The production of Portland cement is however expensive, energy intensive, and results in globally significant greenhouse gas emissions. Natural pozzolans such as pumice can be used as a partial replacement for Portland cement in concrete, which can reduce production costs and greenhouse gas emissions, and improve concrete performance. A fluvial pumice deposit which may be suited for use as a natural pozzolan has been identified on the floodplains of the Waikato River. A sample was milled in Germany, and returned to New Zealand in two subsamples. These were tested in concrete, with tests divided into four rounds. The first two rounds established baseline concrete strengths at water/binder (w/b) ratios of 0.6 and 0.5, with pumice replacing cement at 5, 10, 15 and 30%. Round Three assessed the use of high pH mix water (pH=12.9), and Round Four assessed the use of a polycarboxylate superplasticiser, both with 10% pumice. Pumice is known to retard early concrete strength, however through optimisation of mix design, improvements in concrete strength and durability can be made. Indeed, all 28 day concrete strengths in this research were below Ultracem, however half of these achieved or exceeded Ultracem strengths at 91 days. The use of superplasticiser achieved the best 28 day concrete strengths, and dosage optimisation is expected to yield further improvements. Concrete durability was tested at w/b=0.5, with 10% and 30% pumice. After prolonged curing (231 days), composite concrete showed substantial improvements in electrical resistivity and resistance to chloride attack, most notably with 30% pumice. Concrete porosity was essentially unaffected. This pumice has shown significant promise as a partial cement replacement. Further mix optimisation is likely to yield greater improvements in concrete strength and durability, and will provide a more economically and environmentally sustainable product for the New Zealand concrete market.

Abstract:
Thesis (S.M.)--Massachusetts Institute of Technology, Dept. of Civil and Environmental Engineering, 2012.<br>Cataloged from PDF version of thesis.<br>Includes bibliographical references (p. 73-76).<br>Cement is a very valuable commodity as it can be used to construct structurally sound buildings and infrastructure. However, in many developing countries cement is expensive due to the unavailability of local resources to produce enough cement in-country to meet the demand for this material, and therefore it has to be imported. In rice-producing countries rice husk ash-a material naturally high in silica-can be used as a supplementary cementitious material and can substitute a portion of Portland cement in concrete without sacrificing the compressive strength. This study investigates the use of Cambodian rice husk ash in 10, 20 and 30% replacements of Portland cement by mass in mortar, without optimization of the ash by controlled burning. Five ashes collected from different sources in Cambodia were assessed for their suitability for use in rural Cambodian construction via compression strength testing of 2" (50 mm) mortar cubes. A 20% replacement of unprocessed Cambodian rice husk ash was deemed appropriate for use in small-scale, rural structural applications. Low-tech methods of grinding the ash were also investigated and were found to drastically increase the compressive strength of RHA-cement mortars in comparison to mortars made with unground RHA.<br>by Dorothy Kamilah Brown.<br>S.M.

Abstract:
The use of asbestos fibres in construction products has been banned in European countries for about two decades due to its effect on human health. At present, many developing countries use asbestos cement board as one of the most important construction products for roofing, cladding and partition walls. The Hatschek process is the most commonly used method to produce asbestos Fibre Cement Board (FCB). There are two major problems for the asbestos FCB manufacturers in replacing their products with non-asbestos FCB. The first one is finding materials and fibres that are available and competitive in price compared to asbestos fibres, and the second is providing inexpensive machines and equipment to produce non-asbestos FCB. In this research, an effort has been made to solve these two major problems. After the initial laboratory investigations on several natural and synthetic fibres some of the fibres with potential use in FCB were chosen for the further investigations. A slurry vacuum dewatering process was then designed and made for the laboratory use. The performance of material selections and mix designs selected from the laboratory studies were subsequently verified with factory Hatschek process in a factory site trial. Many specimens with natural and synthetic fibres incorporating silica fume and limestone powder were made and tested in the laboratory. Silica fume and limestone powder were used for enhancing flexural strength and suppression of alkalinity to reduce breakdown of the cellulose fibres. The results of mechanical, physical and II durability tests were analysed. The microstructure of the fibres and composites was also studied by SEM (Scanning Electron Microscopy). At some stages, mix design optimization was carried out to gain the highest flexural strength. The most suitable mixes were chosen for the factory site trials. A number of full-scale non-asbestos trial boards were made successfully in an asbestos FCB factory and tested in accordance with the current national and international standards. The results indicated that the trial boards fulfilled the requirements of the relevant standards. Based on the outcome of this research, a combination of acrylic fibres and waste cardboard in a mix incorporating silica fume and limestone powder in addition to Portland cement can be used to replace asbestos fibres. Although broadly compatible with the asbestos cement production process, this formulation change will necessitate some changes to the existing production lines in asbestos cement factories to produce non-asbestos FCB.

Abstract:
Cement replacement materials are by-products used to produce high performance concrete. Published data on the effects of combinations of mineral admixtures in concrete on the microstructural and performance-related properties under different curing regimes are comparatively little. Further the correlation of strength of concrete to its permeability and pore structure is also not clear. The main objective of this research is to study the performance of various combinations of fly ash/silica fume and slag/silica fume concretes under three different curing regimes, viz. continuous moist curing, no moist curing after demolding and air drying after 7-days of initial moist curing. Six different concrete mixes were prepared with ordinary portland cement and a blend of portland cement and combinations of fly ash+silica fume and slag+silica fume The water-to-cementitious materials ratio of all the concrete mixtures was kept constant at 0.45. The properties investigated included workability of the fresh concrete, engineering properties such as cube and modified cube compressive strength, flexural strength, dynamic modulus of elasticity, pulse velocity, shrinkage and swelling, permeability and microstructural properties such as porosity and pore size distribution. The results show that prolonged dry curing results in lower strengths, higher porosity, coarser pore structure and more permeable concretes. It was found that the loss in early age compressive strength due to incorporation of fly ash or slag can be compensated for by the addition of small amounts of silica fume. The engineering and microstructural properties and permeability of concretes containing fly ash or slag appear to be more sensitive to poor curing than the control concrete, with the sensitivity increasing with increasing amounts of fly ash or slag in the mixtures. The incorporation of high volumes of slag in the concrete mixtures refined the pore structure and produced concretes with very low porosity and threshold diameters. The results emphasize that a minimum 7-day wet curing is needed for concrete with mineral admixtures to develop the full potential, and that continued exposure to a drying environment can have adverse effects on the long-term durability of inadequately cured slag or fly ash concretes. The results also confirm that compressive strength alone is not an adequate index to judge the performance of concrete, and the knowledge of the strength, pore structure and permeability are required for this purpose. Slag/silica fume concrete mixtures showed better performance than fly ash/silica fume concrete mixtures as regards the development of engineering and microstructural properties.

Abstract:
AbstractThe continuous increase in demand for cement in the construction industry critically contributes directly to the global carbon dioxide (CO2) emission. Hence, numerous attempts are being made to reduce CO2 emissions in conjunction with cement production, named as low-carbon cement. This has boosted the enthusiasm for searching for alternatives, specifically supplementary cementitious materials (SCM) that are considered the most environmental and economical friendly method for mitigating CO2 emissions associated with the cement-based construction industry. The purpose of this study is to investigate silicon manganese slag (SiMn slag), a by-product of the metal industry as a sustainable alternative for partial replacements with traditional cement. An experimental investigation was conducted utilizing SiMn slag, primarily focusing on evaluating the compressive strength at 3, 7, 14, and 28 days for both binary and ternary sets of binders, the latter being coupled with ground granulated blast furnace slag. The study has investigated the different replacement levels of cement with SiMn slag up to 90% while maintaining water to binder ratio at 0.35. The microstructure and mineralogical analyses of the prepared hardened binders have been conducted using scanning electron microscopy (SEM) and X-ray diffraction (XRD) to identify phases, morphological changes, and various reaction products. The results indicate that the investigated binary mixture at 30% and 50% cement replacement levels, as well as the ternary mixture at a 50% cement replacement level, exhibited better compressive strength performances. The study suggests using SiMn slag as a supplementary cementitious material in binary or ternary mixtures, potentially achieving improved compressive strength even with higher levels of cement replacement.

Abstract:
AbstractThis investigation is focused on the observation of changes in the properties of polymer-modified cement mortars caused by the addition of recycled glass. The current requirements for reducing CO2 emissions in the production of cement composites, are also forcing the producers of polymer-modified mortars (PMMs) to use alternative materials, such as silica-rich supplementary materials. Selected types of recycled glass with pozzolanic behavior were specifically ground (particle size below 63 μm) and used as a partial cement substitute (10 wt.%, 20 wt.% and 30 wt.% substitution of Portland cement). In order to explain the obtained results and garner new knowledge of the microstructure of the mixtures being studied, the following tests were performed: scanning electron microscopy (SEM) observation, differential thermal analysis (DTA) and high-pressure mercury intrusion porosimetry. The findings show that the finely ground recycled glass has high potential to be used as an effective cement replacement for PMM materials, that are currently used in large amounts, mainly in the rehabilitation of concrete structures.

Abstract:
Annually, in the United States there are roughly 352,000 incidents of hip fractures [1], 300,000 total hip replacements, and 270,000 total knee replacements, most of which are in adults over age 50 [2]. During rehabilitation, patients who have undergone total knee or hip replacement, cartilage cell transplant, cruciate ligament replacement, meniscus debridement, or complex fracture repairs may be instructed to restrict weight bearing. Partial weight bearing (PWB) includes everything from toe-touch to strict PWB (10–50% of the patients’ body weight), to full weight bearing as tolerated [3]. The restrictions following a hip replacement with a cement-less implant typically require a 6-week PWB regimen [4].

Abstract:
Abstract. Cement being a major contributor to carbon emission needs a revolution in its production or modification to the existing cement. One such way to reduce cement usage is to replace the cementitious compound with a suitable material that does not alter the original purpose of cement in concrete. The sugarcane bagasse ashes (SCBA), which are ashes from biomass burning, are found to act as supplementary cementitious material. Moreover, studies were conducted to relate the strength and durability of concrete by the percentage of replacement of sugarcane bagasse ash to cement. The studies revealed that the SCBA imparts more strength to cement at 10% replacement when compared to 20% replacement. However, this study is intended to use 20% of SCBA replacement in cement by adding silica fume. Concrete being mainly reinforced with steel has the problem of corrosion. To overcome the problem of corrosion as well as to reduce the use of cement and to attain the compressive strength of 10% replacement of SCBA. This experiment is intended to analyze the behavior of concrete up to 20% replacement of SCBA with silica fume at different concentrations such as 0%,5%,10%,15%.

Abstract:
ABSTRACT: This study focuses on investigating the potential integration of red mud, a by-product from aluminum production, as a component in the oil well cementing process, with the aim to contribute to the oil and gas industry's sustainability efforts. A variety of experimental approaches were undertaken to develop cement slurries by blending Saudi Class G cement with red mud in a ratio of 90/10. The purpose of this specific blend was to determine the feasibility of using red mud as a sustainable, quality-maintaining alternative in cement formulations. The study included a detailed analysis, adjusting the content of viscosifying agents and fluid loss prevention additives to refine the properties of the slurry, seeking ideal cement properties. The objective was to engineer a cement slurry with a density of 15.8 ppg. Rigorous assessments scrutinized the slurry's rheological properties and the duration required to reach the thickening time. Preliminary results revealed that blends of only Class G cement with red mud fell short of meeting the industry benchmarks. Conversely, when retarders and viscosifiers were precisely incorporated into the mixture, enhanced performance of the slurry was achieved that complied with the exacting oil well cementing standards. These advancements are noteworthy as they indicate red mud's capacity to support environmentally sustainable cementing methods without compromising the essential attributes of performance. Consequently, the study advocates for red mood as a viable and responsible choice for inclusion within the repertoire of materials used by the oil and gas industry. 1. INTRODUCTION The rising levels of carbon dioxide (CO2), a significant contributor to the Earth's greenhouse effect, are causing widespread concern due to their role in exacerbating global warming and the resulting shifts in climate patterns (Markewitz et al., 2012). This troubling trend has highlighted the urgent need for effective CO2 management strategies to address the growing environmental impact. Consequently, the international community is increasingly focusing on how to best dispose of this potent greenhouse gas (Ahmed Ali et al., 2020; Lal, 2004; Patrinos &amp; Bradley, 2009; Weiss, 2021). The oil and gas industry stands at a crossroads, compelled by environmental concerns and economic imperatives to seek innovative solutions that balance sustainability with operational efficiency (Chernova et al., 2021; Jafarinejad, 2017; Skea, 1992). Cement plays a critical role in oil well construction, providing structural integrity and zonal isolation. However, conventional cement production methods rely heavily on finite natural resources, often resulting in significant environmental impact (Al-Dadi et al., 2014; Chen et al., 2010; Habert, 2014; Mohamad et al., 2022). In this context, the exploration of alternative raw materials becomes imperative to mitigate environmental degradation and enhance resource efficiency (Ali et al., 2023; Fakher et al., 2023; Mahmoud &amp; Elkatatny, 2020).

Abstract:
Fly ash is a by-product of coal combustion, made up of particles that are collected through various methods. This by-product has been used successfully as a partial Portland cement replacement in concrete, but the performance predictions of fly ash in concrete have been difficult to predict, especially at high fly ash replacement rates. This study focuses on comparing the performance of concrete with a variety of fly ash mixtures as well as the particle distribution and chemical makeup of fly ash. The slump, unit weight, compressive strength, and isothermal calorimetry tests were used to measure the performance of concrete at 0%, 20%, and 40% fly ash replacement levels. The particle distribution of fly ash was measured with an automated scanning electron microscope. Additionally, the major and minor oxides from the chemical makeup of fly ash were measured for each mixture and inputted into a table. The particle distribution and chemical makeup of fly ash were compared to the performance of slump, unit weight, compressive strength, isothermal calorimetry, and surface electrical resistivity.

Abstract:
Silica fume (SF) influences the hydration rate of Portland cement in different ways depending on the physical and chemical properties of the SF. This study reports the impact of SiO2 content (%), loss on ignition (%), and Brunauer–Emmett–Teller (BET) specific surface area on the hydration reaction of SF-cement paste mixtures. This study used five types of SFs with varying SiO2 content, loss on ignition (%), and particle morphology. Five SFs were mixed with Class H oil well cement at each of two different replacement levels (20% or 30% by mass), and the released heat of hydration was measured using isothermal calorimetry. The results were used to improve the pozzolanic reaction simulation feature of the original Virtual Cement and Concrete Testing Laboratory (VCCTL) software, which enabled the soft-ware to simulate a higher SF replacement ratio in a cement mixture with higher fidelity. Results showed that a silica fume’s SiO2 content (%), loss on ignition (%), and BET specific surface area significantly influence the heat release rate. The new simulation model agrees well with the measurements on all the pastes tested.

Abstract:
High-volume fly ash concrete (HVFAC) has improved durability and sustainability properties at a lower cost than conventional concrete, but its early-age properties like strength gain, setting time, and air entrainment can present challenges for application to concrete pavements. This research report helps with the implementation of HVFAC for pavement applications by providing guidelines for HVFAC mix design, testing protocols, and new tools for better quality control of HVFAC properties. Calorimeter tests were performed to evaluate the effects of fly ash sources, cement–fly ash interactions, chemical admixtures, and limestone replacement on the setting times and hydration reaction of HVFAC. To better target the initial air-entraining agent dosage for HVFAC, a calibration curve between air-entraining dosage for achieving 6% air content and fly ash foam index test has been developed. Further, a digital foam index test was developed to make this test more consistent across different labs and operators. For a more rapid prediction of hardened HVFAC properties, such as compressive strength, resistivity, and diffusion coefficient, an oxide-based particle model was developed. An HVFAC field test section was also constructed to demonstrate the implementation of a noncontact ultrasonic device for determining the final set time and ideal time to initiate saw cutting. Additionally, a maturity method was successfully implemented that estimates the in-place compressive strength of HVFAC through wireless thermal sensors. An HVFAC mix design procedure using the tools developed in this project such as the calorimeter test, foam index test, and particle-based model was proposed to assist engineers in implementing HVFAC pavements.

Abstract:
This report provides summary data and outcomes for hip, knee and shoulder prosthesis types with no or minimal use in Australia. There are two classes of hip replacement no longer used: partial resurfacing and thrust plate. These are defined in the following section on hip replacement. These two classes of implants have not been used since 2014 and 2012, respectively. There are two bearing surfaces used in total conventional hip replacement that have no or little use: procedures performed with ceramic heads on metal bearings and procedures performed with metal heads on ceramic bearings. The rates of revision, reasons for revision and types of revision for procedures using ceramic head/metal bearings are provided. The number of procedures using metal heads/ceramic bearings is very low, so only a summary is provided for this combination. There is one prosthesis type used in total conventional hip replacement that has minimal use: exchangeable neck prostheses. The proportion of procedures using exchangeable necks continues to decline. There are three classes of partial knee replacement that are no longer used: Partial resurfacing, unispacer and bicompartmental. These are defined in the second section of this report on knee replacement. Unispacer and bicompartmental have not been used since 2005 and 2012, respectively. Partial resurfacing is also no longer used with the last procedure recorded in 2022. There is one class of shoulder replacement no longer used: total resurfacing anatomic. This class is defined in the section on shoulder replacement. Total resurfacing anatomic shoulder replacement was last used in 2020. This Report is one of 14 supplementary reports to complete the AOANJRR Annual Report for 2024.
