Comparative Study Using Rice Husk and Its Ash as Natural Coagulants in Waste Water Treatment Anjitha.A, Duithy Goerge. Abstract. This study presents the usage of waste materials (ashes and non ashes) to treat the turbid water for safe drinking for reuse. The effect of rice husk ashand its dust on turbid water are evaluated.
Rice husk ash (RHA) possesses high pozzolanic activities and very suitable as partial replacement of cement in concrete. This paper presents a comparative study on use of RHA as partial replacement of cement in concrete specimens.
Hwang Chao-Lung et al.(8) carried out the research work on effect of rice husk ash on the strength and durability characteristics of concrete. The work investigated the effects of adding residual rice husk ash (RHA) from South Vietnam, generated when burning rice husk pellets in the boiler, to cement.

Natural fibers from agricultural wastes are finding their importance in the polymer industry due to the many advantages such as their light weight, low cost and being environmentally friendly. Rice husk (RH) is a natural sheath that forms around rice grains during their growth. As a type of natural fiber obtained from agroindustrial waste, RH can be used as filler in composites materials in.
The objective of this paper is to study design and operation analysis of down-draught, open core gasifier which uses rice husk as gasification fual. Its output is about 14 kW and the design consideration is intended for YSD2100 Diesel Engine.
This study was carried in 2012, 2013 and 2014 cropping seasons at Teaching and Research Farm of Faculty of Agriculture and Natural Resources Management, Ebonyi State University, Abakaliki to evaluate the effects of rice husk dust on soil particle size distribution, bulk density, total porosity, hydraulic conductivity and maize grain yield in Abakaliki South Eastern Nigeria.
The disposal of rice husks create environmental problem that leads to the idea of substituting RHA for silica in cement manufactured. The content of silica in the ash is about 92-97%. Research had shown that small amounts of inert filler have always been acceptable as cement replacements, what.
Rice husk ash (RHA) has been used as a highly reactive pozzolanic material to improve the microstructure of the interfacial transition zone (ITZ) between the cement paste and the aggregate in high-performance concrete (Biu et al, 2005).Rice husk ash has also been reported to improve the properties of concrete or cement paste due to the pozzolanic reaction and its role as a micro-filler.
This paper intends to evaluate the influence of content of rice husk fiber and cementitious materials on mechanical properties and thermal conductivity of thermal insulation wallboards. Thermal insulation wallboard contained different mass of rice husk fiber was prepared when the weight of cement, fly ash, cellulose ether, naphthalene superplasticizer, and recycled concrete aggregates was equal.
The potential and efficiency of using rice husk ash (RHA) to add up or partially replace Portland cement in deep cement mixing technique are examined. A series of unconfined compression tests on cement-RHA-stabilized clay are conducted to investigate the influence of RHA on the mixture properties.
