Abstract One percent of the earth’s surface is used for cultivation of rice and it is the staple food for billions of people. In India, rice production is 21.2% of World’s production and ranked second among the top twenty rice producing countries. The Rice-Husk Ash (RHA) is a waste residue from incinerating rice-husk. A high reactive pozzolan is obtained when RHA is burnt under controlled conditions. In this paper, the residual RHA was used as a substitute for cement firstly as Natual RHA (NRHA- without grinding) and secondly as Ground RHA (GRHA). The optimum percentage of replacement of RHA was obtained as 10% by weight of cement for natural RHA replaced concrete and 15% for Ground RHA replaced concrete and corresponding improvement in strength as 4.3% and 11.4% respectively as compared to control concrete. Chloride penetration resistance characteristics of natural and ground RHA concretes are 19% and 52% respectively as compared to control concrete.
