The advancement of concrete technology can reduce the consumption of natural resources and energy sources and lessen the burden of pollutants on environment. Presently large amounts of RHA are generated in Rural and Small Scale Industries with an important impact on environment and humans. In recent years, many researchers have established that the use of supplementary cementitious materials (SCMs) like fly ash (FA), blast furnace slag, silica fume, metakaolin (MK), and rice husk ash (RHA), hypo sludge etc. can, not only improve the various properties of concrete - both in its fresh and hardened states, but also can contribute to economy in construction costs.This research work describes the feasibility of using the RHA waste in concrete production as a partial replacement of cement. This present work deals with the effect on strength and mechanical properties of cement concrete by using RHA. The utilization of RHA in concrete as a partial replacement of cement is gaining immense importance today, mainly on account of the improvement in the long term durability of concrete combined with ecological benefits. RHA collection systems have resulted in improving the consistency of RHA. The use of RHA in concrete as a supplementary cementatious material was tested as an alternative to traditional concrete.The cement has been replaced by rice husk ash accordingly in the range of 0%, 5%, 10%, 15%, and 20% by weight of cement for mix. Concrete mixtures were produced, tested and compared in terms of compressive strengths with the Conventional concrete. These tests were carried out to evaluate the mechanical properties for the test results of 7, 28, 60 days for compressive strengths in MgSO4 solution of 1%,3%,5% and also durability aspect rice husk ash concrete for sulphates attack was tested. The result indicates that the RHA improves concrete durabilityThe workability of concrete with increase in percentages of RHA is determined by Slump Cone test, Compaction Factor test and Vee-Bee test as these tests are suitable for mixes of low workability.
