Abstract - Concrete is most widely used construction material today. Concrete has attained the status of a major building material in all the branches of modern construction. It is difficult to point out another material of construction which is as variable as concrete. . Concrete is the best material of choice where strength, durability, permeability, fire resistance & absorption resistance are required. Rice husk & saw dust are the waste products which are abundantly available & which can be used as a substitute for white cement. Rice husk is an agro-waste material which is produced in about 100 million of tons. Approximately, 20 Kg of rice husk are obtained for 100 Kg of rice. Rice husks contain organic substances and 20% of inorganic material. Rice husk ash (RHA) is obtained by the combustion of rice husk. The aim of this project is to prove that RHA can be easily used as a substitute while replacing slight amount of cement in construction industry.
