Rice husk is an agro-waste material which is available in many parts of India and is produced about 100 million of tones. Rice husk ash (RHA) is obtained by the combustion of Rice husk. The most important property of RHA is that determines pozzolanic activity and is suitable for use in time pozzolana mix and for Portland cement replacement. The paper presents the effect of Rice Husk Ash on the structural behavior (e.g. compressive strength, Flexure strength, Tensile strength) of concrete. For which Concrete mixes were prepared by taking as R.H.A. 5%, 10%, 15% of weight of cement.
