These days because of expansion in a population, the demand of infrastructure is expanding day by day. This prompts the increment in production of cement. In the present scenario the overall cement production is about 4.1 billion metric tons worldwide. This huge amount of production prompts utilization of natural resources and it is very unsafe for environment. Enormous amount of waste by-products are delivered from the manufacturing enterprises, for example, mineral slag, fly ash, silica fumes, rice husk ash and so on. the rice husk ash is an agricultural byproduct which is obtained from the rice mills ,the husk which is obtained from mill is of no use i.e it is not even be used for animals to eat. Hence it is used as a fuel in various big industries the burning temperature is very high hence they are obtained from that .the RHA is very lightweight. The research work here deals with the partial replacement of cement with RHA in concrete at various percentage such as 0%,5%,10%,15%,20% and25% by mass of cement. Various experimental investigations are carried out to find out the compressive strength , split tensile strength and of concrete samples cured for period of 7 and 28 days. the results obtained from the experiments with satisfactory replacement of cement with rice husk ash are presented in this research paper.
