Abstract: Self compacting concrete is one of the new concepts, without using any external vibrations and labors can easily fill the formwork even in difficulty places without segregation. For such cases, SCC possesses good flowability and cohesiveness. In this study, two mineral admixtures were used to improve the required quality of concrete. The main aim of this study is to evaluate the workability and compressive strength property of SCC containing mineral admixtures such as fly ash and alccofine. In this study the replacement of cement with fly ash was kept at 30% for all concrete mixes with varying dosages of alccofine (0%, 5%, 10% & 15%). Different tests such as slump flow, V-funnel & L-box tests were conducted to check the workability of SCC. Compressive strength values of SCC mixes were determined at different curing periods. From the test results, it is observed that the optimum replacement of alccofine can be taken as 10%. The test results indicate that the combination of fly ash and alccofine in cement replacement produce M25 grade concrete.
