The improvement of concrete technology can able to decrease the pollutants on environment and usage of natural resources. This paper explains the usefulness of using Rice husk ash (RHA) in concrete production as a partial replacement of cement. After replacement, this can improve the strength as well as durability properties of concrete. RHA has high reactivity and pozzolonic property and this property depends on temperature. Concrete mixtures were produced and tested both with RHA and without RHA replacement in terms of compressive strength and results have been compared between both of them. 30% replacement of cement with RHA has been done in all cases. Soil stabilization and ground improving techniques have become a important issue in construction field now a days. The common soil stabilization methods are becoming more costly because of high cost of stabilizing agents like lime, cement etc. The cost of the stabilization may be decreased by proper replacement of RHA with suitable proportion. Soil replacement with RHA and also different tests have been conducted to check the effectiveness of RHA in the soil stabilization aspect. So that RHA usage can reduce the cost of the total construction.
