Self - compacting concrete (SCC) has widespread use in the prefabricated concrete industry. Nowadays the demand for concrete with high quality is permanent. The production of such mixes often used expensive admixtures and very large quantity of cement. But such concrete was generally of lower strength and difficult to obtain. This lead to the development of Self Compacting Concrete. The workability properties of SCC such as filling ability, passing ability and segregation resistance are evaluated using workability tests such as slump flow, V-funnel and L-Box tests. The flow ability and segregation resistance of SCC ensures a high level of homogeneity, minimal voids and uniform concrete strength providing the potential for a superior level of finish and thus durability of the structure. The elimination of vibrating equipment improves the environment on and near construction and precast sites where concrete is being placed, reducing the exposure of workers to noise and vibration. This advantages construction practice and performance with reduced health and environment hazards make SCC a highly acceptable one for both precast and cast in situ construction. This paper deals with the history of SCC development and its basic principle, different testing methods to test high- flow-ability, resistance against segregation, and passing ability, benefits and limitations, usage and applications. The self-compacting concretes developed a 28- day compressive strengths ranging from 26 to 48 MPa. The results show that an economical self-compacting concrete could be successfully developed by using red mud. The present project investigates the making of self-compacting concrete more affordable for the construction market by replacing high volumes of Portland cement by red mud. The study focuses on comparison of fresh properties of SCC containing varying amounts of red mud with that containing commercially available admixture. Test results substantiate the feasibility to develop low cost SCC using red mud.
