Use of rice husk ash in concrete - ScienceDirectrice husk ash was prepared as a pozzolana by a special process such that the final product conformed to engineering requirements in terms of physical and chemical properties, and the silica remained in an amorphous form with a minor amount of unburnt carbon. Results indicated that such a pozzolana can be produced with varying pozzolanic activity index depending on the degree of grinding and the burning temperature. The effect of rice husk ash content as partial replacement&nbsp;...【Get Price】

Rice Hull Studio - Earthbag Buildingrice hulls can be used as a fill material to build with. These unasumming little bits of of debris that are often discarded have found new value as insulation in wood-framed houses and as filler for earthbag projects. They are a durable and renewable material that will not easily burn or decay. They are reported to be about R-3 per inch as insulation, and will not harbor mold or fungus because they don't retain enough moisture to do so. All of this is without any added chemicals...a totally&nbsp;...【Get Price】
