Abstract Concrete with high ductility, workable, high strength, easy to flow without compaction, and durable is a concrete need in the future. Concrete with this quality, one of which is to make self-compacting concrete (SCC). This paper reports performance of self compacting concrete (SCC) containing rice hush ash. Rice husk ash is waste from burning rice husks. The purpose of this study was to determine the performance of SCC concrete with the addition of rice husk ash. SCC specimens were made using rice husk ash (RHA) and SCC without rice husk ash (NRHA). The specimens were made with water cement ratio 0.30. Superplastisizer used is a type Naptha 511P. The result indicated that the workability of SCC containing rice hush ash (RHA) more workable compare SCC without rice hush ash (NRHA). The initial setting time of SCC with rice hush ash more slowly compare SCC without rice hush ash. The compressive strength, flexural strength, and tensile strength of SCC RHA mor higher compare SCC without RHA (NRHA). The tensile strength value of RHA and without RHA concrete meets the tensile strength requirements of RSNI T-12-2004.

Rice husks (RH) are agricultural wastes available abundantly in rice producing country. A by-product obtained from combustion of rice husk is rice husk ash (RHA) which is rich in silica (SiO2) contents. This paper focused on the effect of acid leaching treatment on rice husk to produce high-purity silica. There are 4 different states of conditions involved; raw rice husk (RRH), treated rice husk (TRH), rice husk ash (RHA), and treated rice husk ash (TRHA). Citric acid; C6H8O7 was used as a leaching agent. TRH and TRHA was leached to see whether treated rice husk before combustion (TRH) or treated rice husk after combustion (TRHA) will produce more high-purity silica. Chemical composition analysis shows high amorphous silica content which is 98.47% with low metallic impurities at 1.0M C6H8O7, 70 oC for treated rice husk (TRH). X-ray diffraction (XRD) pattern shows the presence of amorphous silica in treated rice husk (TRH) and crystalline silica in treated rice husk ash (TRHA). Fragmentation of TRH into small pieces after acid leaching is seen where there is significant increase in the exposed surface areas. High-purity amorphous silica with more than 98% was prepared via citric acid leaching treatment and combustion process.

Alkali activated binder is an innovative material and a potential alternate to conventional Portland cement for use in construction applications. Alkali activated binder is prepared using industrial or agro based by-products such as ground granulated blast furnace slag, fly-ash, rice husk ash, etc. This paper presents the processes and tests involved in evaluation of the strength and workability of slag-rice husk ash based alkali activated concrete. Raw rich hush ash was collected from various sources, ground and tested to attain suitable fineness and use in preparation of the concrete. Blast furnace slag and rice husk ash were incorporated in various percentages to prepare the alkali activated concrete. Results from the tests were compared with that of conventional Portland concrete. The fineness of rice husk as well as the amount played significant role in altering the properties of alkali activated concrete. Porousness of rice husk ash lowers the workability and compressive strength.

Rice husk ash is a kind of volcanic ash material with high silicon. This also provides a feasibility for rice husk ash as cement-based auxiliary cementing material. China is rich in rice husk resources, and the rice husk ash is stacked. Using rice husk ash (RHA) instead of traditional cementitious materials can effectively solve the environmental pollution caused by the accumulation of rice husk ash. Domestic and international scholar have added rice husk ash as mineral admixture to concrete, but the utilization rate is very low. In order to increase the added value of rice husk ash, the high silicon property of rice husk ash was used to solidify soil. The application range of solidified soil is wide, the requirements for materials are not high, and the functions are different, which can realize the extensive use of rice husk ash. This paper summarizes the literature on comprehensive utilization of rice husk ash at home and abroad, systematically expounds the physicochemical properties and production process of rice husk ash, introduces the application of rice husk ash in solidified soil, and points out the unsolved problems in this field, which provides a direction for the further development.

Due to the microbiological resistance of epoxy resins, their disposal after the completion of their lifecycle is a pressing issue. In this respect, the use of biodegradable rice and buckwheat husk derivatives as fillers may improve the service properties of epoxy materials. The results indicate that rice and buckwheat husks, as well as their ashes, can be used by soil microorganisms as a substrate. Compared to buckwheat husks, rice husks increase the biological activity of soil microbiota to a much greater extent. However, compared to rice husks, an increase in the temperature of obtaining rice husk ash leads to a decrease in its use by soil microorganisms as a substrate. This is associated with a decreased content of the X-ray amorphous phase and an increased amount of crystalline minerals in the composition of rice husk ash. At the same time, regardless of the temperature of its production, buckwheat husk ash outperforms buckwheat husks in terms of activated soil respiration, which indicates the possibility of microbiological disposal of buckwheat husk ash during its incubation in a soil. Epoxy materials, both unfilled and filled with rice and buckwheat husk ash, are not used by soil microorganisms as a substrate. At the same time, the filling of epoxy materials with rice husks leads to an improvement in their biodegradability. The biodegradation degree of rice and buckwheat husks, as well as their ashes, determines the effect of these fillers on soil respiration in the presence of epoxy materials.

Abstract Nanoparticles of polyvinyl alcohol with rice husk ash as a filler for strong polymer material candidates have been prepared through the sol-gel method. Rice husk ash is a waste product obtained from the combustion of rice husks at a controlled temperature and possesses high pozzolanic properties due to its silica content. Ball milling and co-precipitation methods were employed on the rice husk ash to create nanoparticle materials. To produce nanocomposite membranes, a polyvinyl alcohol solution was utilized as a solvent through the sol-gel method. The nanocomposite samples of rice husk ash were analyzed thermally to determine the material’s response to temperature. Various nanocomposite compositions of polyvinyl alcohol and rice husk ash were used, including 0%, 1%, 2%, 3%, and 4%. Based on the thermal analysis, it is evident that there were changes in enthalpy (H) and mass characteristics in all five samples.

This paper discusses the issue of utilization of rice and buckwheat husks, a comparison of their modifying effect in epoxy antifriction coatings, for this, the elemental composition of these fillers was determined using X-ray fluorescence analysis, their structure was analyzed by scanning electron microscopy, and the acid-base characteristics of the filler surface were determined by the pH method., the surface area of the pores of the ash of rice and buckwheat husks, their oil absorption were calculated, a sol-gel analysis was carried out to assess the density of the spatial network of filled epoxy coatings, and their wear resistance and hardness were determined.
In the course of the research, the optimal temperature for obtaining ash from rice and buckwheat husks was established, which contributes to an increase in wear resistance, hardness and a decrease in the static friction coefficient of filled epoxy coatings. It is shown that the optimal temperature for obtaining rice husk ash is 500 C, and buckwheat husk ash 800 C.
At the same time, rice husk ash is a more effective filler for epoxy polymers than buckwheat husk ash, since it increases the hardness of materials and provides a greater decrease in their friction coefficient.

When properly processed, rice husk ash (RHA) comprises a large amount of SiO2, which exhibits a high pozzolanic activity and acts as a good building filler. In this paper, the effects of rice husk ash content, acid pretreatment, and production regions on the compressive and flexural properties and water absorption of a cement paste were studied. The experimental results showed that the compressive strength of the rice husk ash was the highest with a 10% content level, which was about 16.22% higher than that of the control sample. The rice husk after acid pretreatment displayed a higher strength than that of the sample without the acid treatment, and the rice husk from the Inner Mongolia region indicated a higher strength than that from the Guangdong province. However, the flexural strength of each group was not significantly different from that of the blank control group. The trend observed for the water absorption was similar to that of the compressive strength. The variation in the RHA proportions had the greatest influence on the properties of the paste specimens, followed by the acid pretreatments of the rice husks. The production regions of the rice husks indicated the least influence.

The high need for polymeric materials and the availability of agro-industrial wastes, such as the rice production chain, demand the development of technologies to obtain polymeric composites based on these waste materials. Therefore, this work aims to develop materials using low density polyethylene (LDPE) as a polymer matrix and rice husk or rice husk ash, prepared by micronization in a whirlwind mill, as reinforcing fillers. The processing was carried out by injection molding, with formulations containing 20%, 30% and 40% of the filler. Tensile strength, hardness and water absorption properties were evaluated. The tensile strength of composites containing rice husk ash was higher than the same parameter for composites containing rice husk as filler. The highest tensile strength of 9.26 N/mm² was found for the material containing 20% of rice husk ash. The shore D hardness of materials containing rice husk ash was slightly higher. Regarding water absorption, the composites containing rice husk ash were those with lower absorption and all developed materials presented water absorption below 1.1%. Based on the results, we concluded that the composites have potential properties for the manufacture of polymeric consumer goods.

Rice husk ash is a waste of rice husk combustion with pozzolanic properties and contains relatively high silica. Therefore, rice husk ash can be used as a cement substitute to manufacture concrete. This study aims to determine the performance of rice husk ash as a clinker substitute for the compressive strength of the K400 concrete produced. Rice husk ash used in this study was first ground to pass a 45 mm sieve. Then the K400 concrete mix design was made with three variations of adding rice husk ash: 0%, 10%, and 20% of the total cement consumption. The tests carried out on the test objects included slump testing and compressive strength testing for concrete aged 3, 7, 28 days. Slump flow testing is carried out to see the ease of work. At the same time, compressive strength testing is carried out to determine the quality of the concrete itself. Based on the Compressive Strength tool observing, adding rice husk ash, as much as 10% has a strength value that reached the standard compressive strength determined at 28 days. On the other hand, adding rice husk ash more than 10% produces a lower compressive strength of concrete than the standard.

Abstract It is well known that animal fiber is one of the potential pollutants to the environment if not been well disposed. Besides animal fiber, rice husk ash has also been considered as a type of waste that are able to pollute the air and soil. Recently, there are plenty of research for the purpose of reusing this type of waste in the composite making. It has been established that irradiation on composite at dose of more than 3 kGy can potentially increase the properties of the composite as it becomes harder and able to hold huge loads. Therefore, this research is conducted to study the effect of irradiated composites of sheep wool fibers reinforced with rice husk ash. The composites were prepared with different percentage of sheep wool (3% and 5%) as well as the addition of rice husk ash as filler. The gamma irradiation of 7 kGy of dose is used on the composites and later analysed for the changes in the chemical and physical properties. New chemical bonds were observed for irradiated composites through Fourier-transform infrared spectroscopy (FTIR) analysis. Irradiated composite with 5% of wool has higher strength (0.16 MPa) compared to the irradiated composite with 3% of wool (0.09 MPa) from Izod fracture test. Meanwhile, composite without rice husk ash added were measured to have higher strength compared to the addition of rice husk ash as filler for both unirradiated and irradiated samples. The addition of rice husk ash increased the brittleness of the composite. In conclusion, the sheep wool fibers without the addition of rice hush ash are suitable to be used as reinforcing fibers in composites with gamma irradiation play insignificant part of the composite’s strength.

Durability of asphalt pavements is related to choosing proper materials. Fillers as the smallest particles of stone materials, and one of the most important parts of asphalt mixtures, exert pivotal effects on the performance of asphalt mixtures, by filling empty spaces and because of their softness, surface features and chemical compounds. Rice husk ash is one of the waste products of burning rice husk in powerhouses that is accounted as biomass. Recently, a good many of investigations have shown that rice husk ash, as a high quality pozzolan, can be properly replaced of common aggregates. In this study rice husk ash was used as filler in hot mix asphalt, and the result mixtures’ mechanical properties was compared with ordinary mixtures whose filler was stone powder. Asphalt mixture samples with two different aggregate graded, and 0, 25, 50, 75 and 100 percent of rice husk ash which were the substitution of stone powder content, were made and the effects of using rice husk ash on the moisture sensitivity, resilience modulus, rutting and dynamic creep of asphalt mixtures were investigated. The results demonstrated that increase of using rice husk ash as the replacement of prevalent fillers in hot mix asphalts, noticeably improves their performance; however, because of excessive stiffness created by rice husk ash, it's better to use it in optimized percentage. Accordingly, statistical analysis of the tests’ results leads to presenting an optimized model for the content of Rice Husk Ash to be used in hot mix asphalt. Finally, Rice Husk Ash content were suggested 26% for graded number 4 and 48% for graded number 5 as replacements for stone powder filler.

The highest content in rice husk is ash with its main component of silica. Silica in ash causes the low adsorption capacity. Activated carbon from rice husk can be obtained by lowering the ash content. The aim of this study is determine the effect of particle size of charcoal and reflux time the ash content using a solution of potassium carbonate. The activation of rice husk char was carried out by using reflux methods with a potassium carbonate solution. The resulted carbon was washed using hydrochloric acid tested using iodine and methylene blue to examine of its adsorbance. The particle size of rice husk and reflux time decrease ash content in rice husk. In general, husk with the size of 80 mesh can produce carbon with low ash content and high absorption using reflux time at least for 120 minutes. Rice husk size of 100 mesh refluxing with potassium carbonate for 150 minutes can reduce the ash content as 91.85% and adsorptivity of the iodine at 331 mg.g -1 .

Rice husk ash and rice straw ash are common agricultural wastes in developing countries. Currently, utilizing these wastes in the construction sector such as soil improvement and cement concrete production is a trend in many areas around the world. In Vietnam, with a rice production of more than 40 million tons/year, millions of tons of rice husk ash and straw ash can be generated. This is an abundant and a cheap material source. This article will research and evaluate the potential of rice husk ash and straw ash for soft soil improvement in Vietnam. Research results show that straw ash and rice husk ash are materials having high pozzolan activity. Various studies in the world and some studies in Vietnam showed that rice husk ash and straw ash not only improve some physical and mechanical properties of soil but can also partially replace the amount of binder. Vietnam has different types of soft soil and construction activities are increasing, so the demand for improving soft soil is also increasing. In which, improving soil with cement binder is one of the most popular methods. Therefore, rice husk ash and rice straw ash have great potential to combine with cement in improving soft soil in Vietnam. Utilizing these wastes not only helps reduce the negative impact their causes on the environment but also helps improve construction quality and reduce construction costs.

In this paper, the rice husk ash and crumb rubber powder were used as a combined modifier for asphalt. The impact of the aging on the physical and rheological properties of crumb rubber powder, rice husk ash, and the combined modified asphalt was studied through the rolling thin film oven (RTFO) simulations. A Fourier-transform infrared Spectroscopy (FTIR) test was used to study the aging mechanisms of the combined crumb-rubber-powder- and rice-husk-ash-modified asphalt before and after aging through the changes in functional groups. Impacts of the combined, crumb rubber powder, and rice husk ash modifiers on the anti-aging characteristic of the asphalt binder were analyzed through different aging indices and the variations in intensity of the absorption peaks. According to the combined results, the addition of the combined crumb rubber powder, and rice husk ash could enhance the thermal oxidative aging resistance binder. Moreover, the optimal content of composite modified asphalt was (7% rice husk ash + 10% crumb rubber powder). In addition, the combined modified asphalt binder had all the peaks of neat asphalt, rice-husk-ash-modified asphalt, and crumb-rubber-powder-modified asphalt and no appearance of new peaks. A scanning electron microscope (SEM) test was carried out to observe the microstructure of the combined crumb-rubber-powder- and rice-husk-ash-modified asphalt binders. The obtained result demonstrated that different SEM images showed that the combined crumb rubber powder, and rice husk ash modifiers were uniformly dispersed inside the asphalt binder and consequently leading to format a homogeneous blended binder.

Asian countries rely massively on rice to feed and sustain its massive population. For long the staple food has provided nourishment to the masses and the classes. Rice is grown in large quantities in Asian countries. A by-product of its cultivation is its husk. The husk of the rice grain is mainly utilized as a fuel for the boilers in the rice mills. The uncontrolled burnt rice husk referred to as rice husk ash consists majorly of silica. silica is used in a wide variety of commercial and industrial applications. Use of rice husk ash in various products serves to reduce the pollution caused by its pileup in localities especially close to the rice mills. More sustainable and an affordable source of Si would benefit the society rather than disposing rice husk ash in the fields and landfills. This brief review provides insights into the synthesis, applications, and properties of rice husk ash incorporated products either directly in the as received conditions or under modified conditions.

The soil used for the main material of red brick is sandy clay soil. The advantage of red brick is that it is resistant to hot weather or fire because it has undergone the combustion process. However, new innovations are necessary for the red brick manufacturing process due to the reduced soil. The innovation carried out in this study was adding the main material with fly ash and rice husk ash. The purpose of this study was to obtain red brick mixture fly ash and rice husks with increased compressive strength than normal red bricks. The research method used is an experimental method with the addition of fly ash and rice husk ash by 4%, 8%, and 12% of the soil weight. The results obtained from this study are red bricks with fly ash and rice husk ash produced the highest value in the fly ash mixture of 12% (in sample D2) content of 75.07 Kgf / cm² so as to improve the quality of conventional red bricks.

This paper for the first time investigates the workability, compressive and tensile strength of concrete containing Fly Ash, Rice Husk Ash and Waste Glass Powder. Seventy six cube specimen (150 150 150 mm were cast with different composition of Fly Ash, Rice Husk Ash ,Waste Glass Powder and steel fibers. The cubes were tested for axial compression and tensile tests. The research also investigated the effect of curing regime on the compressive and tensile strength of concrete cube specimen. The results revealed that the addition of 15 % Rice Husk Ash and 39% Fly Ash increased the workability of 25 % as compared to the controlled concrete. The sample containing 10 % Rice Husk Ash, 10% Waste Glass Powder and 39% micro silica produced worst workability as it decreased the workability up to 5 % of controlled concrete. The results for axial compressive strength shows that the addition of 15% Rice Husk Ash (RHA) and 39% of Fly Ash (FA) in concrete leads to the improvement of compressive strength by 14%. The sample containing replacement of 10% Rice Husk Ash (RHA), 10% waste glass powder (WGP) and 39 % of micro silica (MS) in concrete leads to the improvement by 53.9 for compressive. The replacement of 10% Rice Husk Ash (RHA), 10% waste glass powder (WGP ), 39 % of micro silica (MS) 3% steel fiber in concrete leads to the improvement by 37% for compressive strength. It was observed from the results of tensile strength that the samples containing 15% Rice Husk Ash (RHA) and 39 % of Fly Ash (FA) increased the tensile strength by 24% as compared to the controlled concrete. The sample containing replacement of 10% Rice Husk Ash (RHA), 10% waste glass powder (WGP) and 39 % of micro silica (MS) in concrete leads to an increase of 20% as compared to the controlled ones. Also, the replacement of 10% Rice Husk Ash (RHA), 10% waste glass powder (WGP), 39 % of micro silica (MS) 3% steel fiber increased the tensile strength by 40 % as compared to the controlled concrete sample. Finally, it was concluded that the replacement of 10% RHA, 39% micro Silica, 10% WG in concrete was found to be superior for increasing the mechanical properties of concrete.

Rice mills produce abundant husk waste. The husks are used as a mixing material for bricks because they are flammable and have capability to form hot coals with high calor. This potential is used to develop the husks into briquettes. This study used rice husks (oriza sativa) and flamboyant pods (Royal ponciana) as the main ingredients for forming briquettes. This pods was chosen because had not optimally used. The composition of rice husk briquettes and flamboyant fruit skins made of 16.7%: 83.3%, 33.4%: 66.6%, 50%: 50%, 66.6%: 33.4%, 83.3 %: 16.7%. The briquettes formed were measured the calorific value, mass reduction using the TGA (Thermogravimetric analysis) thermal measurement method, and measured the values of moisture, ash, volatile, and fixed carbon content. The results of the measurement of the lowest calorific value in rice husk briquettes were 83.3% with a value of 4,551 cal / gram, while the highest value was 5,945 cal / gram in rice husk briquettes percentage of 16.7%. The result of TGA measurement of the largest mass reduction was briquettes with a percentage of husk 83.3% having the highest mass reduction of 11.1 mg. The results of the measurement of water content obtained 7.04%, 24.70% volatile, 9.98% ash content, 58.28% fixed carbon

The development of infrastructure in Indonesia is currently very increasing, The use of concrete is widely used to build dams, buildings, roads, bridges and others. Concrete is used because it has advantages over other materials, apart from having compressive strength, concrete is also a relatively inexpensive material. However, the increasing amount of cement used in the manufacture of concrete will cause an increase in global warming. Thus, geopolymer concrete was introduced as an alternative to reduce cement consumption in concrete work. The purpose of this study was to determine the effect of using rice husk ash and borax as an alternative material on the compressive strength of concrete and to determine the effect of using rice husk ash and borax as an alternative material to slow the setting time of geopolymer concrete. The variations in the use of rice husk ash 0%, 10%, 15%, and 20% with the use of 3% borax. From the results of the study, the use of rice husk ash and borax in the geopolymer concrete mixture had an effect on the compressive strength of concrete in this study, with the addition of rice husk ash there was a decrease in compressive strength when compared to normal geopolymer concrete or without a mixture of rice husk ash and borax. The use of 15% rice husk ash and 3% borax achieved the highest compressive strength values when compared to the use of rice husk ash as much as 10% and 20%. Furthermore, the more the use of rice husk ash with the use of 3% borax, the longer the setting time in geopolymer concrete.

In the agricultural countries, rice husk is an abundant waste, especially as one of the largest sources of silica (SiO2) production that can be produced. By complete combustion, to about 87% - 97% SiO2 content can be produced from rice husks. Alkaline solution is used as a solvent in the solid-liquid extraction production of rice husk ash SiO2. The mass of 10 grams of rice husk ash was weighed for the extraction process added with 80 ml of potassium hydroxide (KOH) solution with 10%, 15% and 20% various concentration to extract the SiO2 content. In a systematic study, for 60 minutes the rice husks were soaked and washed using HCl and then heated in a muffle furnace. The results of this study showed that all samples are succeeded in homogenizing SiO2 with purity close to 90%. Furthermore, through Energy-Dispersive X-ray Spectroscopy (EDS) analysis was proven these results obtained through solid-liquid extraction of KOH from rice husks. Natural SiO2, known as biosilica, is useful and has potential in reinforcing compounds, including applications as filler in tires and natural rubber compounds.

Full textAbstract:
A metal–matrix composite was developed by eco-friendly accumulative roll bonding process and agricultural wastes. Amorphous silica particles were obtained by heating rice husk at 600℃ and then ball milling. Amorphous silica particles as a reinforcement were embedded in a matrix of aluminum 1100. Composites with various amounts (1%, 2%, 3%, 4%, 5%, 6%, and 7%, mass fraction) of rice husk ash particles were developed. The produced aluminum–rice husk ash composites were evaluated for structural changes and mechanical properties. The scanning electron micrographs showed a uniform distribution of rice husk ash particles and were bonded well with the aluminum matrix after 10 cycles. By increasing the rice husk ash content, the composite strength increases first and then becomes constant because of the inappropriate connection of aluminum sheets. Increasing the rice husk ash content of the composite causes the change from the ductile to a relatively brittle type of fracture.
