engineering properties of silty soil stabilized with lime and rice Husk Ash and reinforced with waste plastic fiber
2013Co-Authors: Agus Setyo Muntohar, Anita Widianti, Edi Hartono, Wilis DianaAbstract:AbstractAlthough abundant plastic waste contaminating the environment may be utilized as reinforcing materials, a potential pozzolanic material (rice Husk Ash blended with lime) possesses superior properties in stabilizing soils. Engineering behavior of the stabilized clayey/silty soil reinforced with randomly distributed discrete plastic waste fibers is investigated in this paper. The results indicate that the proposed method is very effective to improve the engineering properties of the clayey/silt soil in terms of compressive, tensile, and shear strength, which further enhanced the stability and durability of the soil. Based on the compressive strength, California bearing ratio (CBR), shear strength, and failure characteristics, the optimum amount of fiber mixed in soil/lime/rice Husk Ash mixtures ranges from 0.4–0.8% of the dry mass.

stabilization of residual soil with rice Husk Ash and cement
2005Co-Authors: E A Basha, Hilmi Bin Mahmud, Roslan Hashim, Agus Setyo MuntoharAbstract:Abstract Stabilization of residual soils is studied by chemically using cement and rice Husk Ash. Investigation includes the evaluation of such properties of the soil as compaction, strength, and X-ray diffraction. Test results show that both cement and rice Husk Ash reduce the plasticity of soils. In term of compactability, addition of rice Husk Ash and cement decreases the maximum dry density and increases the optimum moisture content. From the viewpoint of plasticity, compaction and strength characteristics, and economy, addition of 6–8% cement and 10–15% rice Husk Ash is recommended as an optimum amount.

2004Co-Authors: Agus Setyo MuntoharAbstract:Expansive soil has been a problem in Indonesia as in other countries. Current research found that there is a potential use of silica waste%2C resulting from burnt rice Husk%2C as a pozzolanic material. This paper presents the results of study on the utilisation of Ashes produced from uncontrolled rice Husk burnt in Yogyakarta %28Indonesia%29.%0D%0A%0D%0AIn this research%2C a series of laboratory tests has been conducted. The tests were carried out individually or in a combination in which the Rice Husk Ash %28RHA%29 content were varied from 7.5%2C 10%2C and 12.5 percent%2C and the lime content from 2%2C 4%2C 6%2C and 10 percent %28by the dry weight of soil%29. All the samples have been remoulded at their optimum moisture content %28OMC%29 and maximum dry density %28MDD%29.

effect of the cement rice Husk Ash on the plasticity and compaction of soil
2003Co-Authors: E A Basha, Roslan Hashim, Agus Setyo MuntoharAbstract:The chemical stabilisation of soils was studied by using cement and rice Husk Ash. Three types of soils, residual soils, kaolinite and bentonite, were used in the study. The experimental study included the evaluation of the main index properties of the soil and compaction, along with a characterisation of the materials through X-Ray diffraction. Test results show that both cement and rice Husk Ash reduces the plasticity of soils. In term of compactability, addition of rice Husk Ash and cement decreases the maximum dry density and increases the optimum moisture content. From the viewpoint of plasticity, compaction characteristics, and economy, addition of 6 - 8 percent cement and 10 - 15 percent rice Husk Ash are recommended as an optimum amount.

effect of particle size on tribological behavior of rice Husk Ash reinforced aluminum alloy alsi10mg matrix composites
2013Co-Authors: S D Saravanan, M Senthilkumar, S ShankarAbstract:Rice Husk Ash of three different particle size ranges (50–75, 75–100 and 100–150 μm) a 3, 6, 9, and 12% by weight is reinforced with an aluminum alloy (AlSi10Mg) using the liquid metallurgy method. The dry sliding wear behavior of the composites in the cast conditions is examined using the pin-on-disc tribotesting machine for three different loads (20, 30, and 40 N) with three different sliding velocities (2, 3, and 4 m/s). The results reveal that the composite reinforced with the coarse rice Husk Ash particles exhibits superior wear resistance compared to the fine rice Husk Ash particles. The wear rate of the composite decreased with an increase in the weight percentage of rice Husk Ash particles for all size ranges. Finally, the wear mechanism was investigated with the worn surface using a scanning electron microscope.

hydration behavior and mechanical properties of blended cement containing various amounts of rice Husk Ash in presence of metakaolin
2016Co-Authors: M R ShatatAbstract:Abstract This paper reports an experimental study carried out to investigate the effects of metakaolin and rice Husk Ash on the hydration behavior and mechanical properties of blended cement. The results showed that the combination of metakaolin and rice Husk Ash provides a positive effect on mechanical properties. The samples incorporating the ternary blends of cement with 20–15% metakaolin and 5–10% rice Husk Ash showed better compressive strength than that of the normal sample without rice Husk Ash. These blends proved to be the optimum combination for achieving maximum effect.

critical aspects in the handling of reactive silica in cementitious materials effectiveness of rice Husk Ash vs nano silica in mortar dosage
2019Co-Authors: M Torrescarrasco, Julian Jimenez Reinosa, M A De La Rubia, E Reyes, Alonso F Peralta, J F FernandezAbstract:Abstract Nano-silica addition improves mechanical and durability behavior in mortars. However, nanomaterial handling requires use of occupational risk prevention measures as Individual Protection Equipment for the workers. Moreover, the high agglomeration of nanomaterials produces uncertainty in the expected mortar performance. Rice Husk Ash as a source of reactive silica in cement compositions is compared with nano-silica. The use of rice Husk Ash provides similar physical-chemical cementitious materials than other commercial nano-silica providing relevant differences during the composition. Near 50% wt of volatility is found for the silica nanoparticles during the handling dosage. Thus, the rice Husk Ash presents a reduced volatility, ∼12% wt and it allows ensuring high content with adequate workability. Mortars with addition of rice Husk Ash reach higher compressive strength and resistivity in correlation with lower porosity. For that, the use of rice Husk Ash is viable as safer alternative material than nano-silica in the cementitious compositions. In addition, as the rice Husk Ash comes from agricultural waste resources their use as secondary raw material will contributes to circularity in the economy by reducing engineered nanomaterials consumption.

corrosion performance of rice Husk Ash blended concrete
2007Co-Authors: Velu Saraswathy, Hawon SongAbstract:Abstract Rice Husk Ash is one of the promising pozzolanic materials that can be blended with Portland cement for the production of durable concrete and at the same time it is a value added product. Addition of rice Husk Ash to Portland cement not only improves the early strength of concrete, but also forms a calcium silicate hydrate (CSH) gel around the cement particles which is highly dense and less porous. This may increase the strength of concrete against cracking. So far a systematic and detailed investigations on the corrosion performance of rice Husk Ash blended concrete is very scarce. Therefore, in the present investigation, a realistic approach has been made using different techniques such as compressive strength, bond strength, split tensile strength etc. Corrosion performance was evaluated using, open circuit potential measurements, rapid chloride ion permeation test and impressed voltage test and the results were discussed.
