Self-compacting concrete (SCC) is a relatively new technology that does not require any vibration for placing and compaction which gives lot of economical and technical benefits. It is able to flow under its own weight, completely filling formwork and achieving full compaction, even in the presence of congested reinforcement. SCC has favourable characteristics such as high fluidity, good segregation resistance and the distinctive self-compatibility without any need for vibration during the placing process and so noiseless construction. In this study first the properties of a normal SCC M30 mixwas evaluated. Then mixes with 5%, 10%, and 15% replacement of cement with Alccofine was prepared and optimum percentage was determined by studying the fresh and mechanical properties and comparing it with Normal SCC mix. Optimum percentage was selected as 10%. By making the Optimum percentage of Alccofine constant and varying the Micro steel fiber by 0.5%, 1%, 1.5% another mixes were prepared. This SCC mix will be compared with normal SCC. Fresh properties of the SCC will be tested for slump flow diameter, L-box height ratio, and V-funnel flow time. Hardened properties of SCC will be studied for compressive strength, flexural strength and splitting tensile strength. By studying the compressive strength of different mixes it was observed that all SCC with both Alccofine and Micro steel fibre gave high strength than normal SCC mix. When comparing the Split tensile strength also SCC with Alccofine and Micro steel fibre gave highest result. Flexural strength also gives satisfactory results.
