Abstracts: A high performance concrete is something which demand much higher performance from concrete compared to performance expected from routine concrete. High performance concrete is achieved in practice by using selection of raw material (mineral admixture/ chemical admixture) & appropriate mix design the desire performance objective. Our aim of the project is find the optimum value of mineral admixture for M-50 grade concrete by using and comparison of different admixture silica fume. The project is to find out the dosage of these minerals in M-50 grade concrete which gives the high strength & high workability in high performance concrete in minimum and maximum time duration. Most high- performance concrete have a high cementation content and a water cementations material ratio of 0.40 or less. A supplementary cementation material such as silica fume is often used in high performance concrete. all these materials increase the modulus of elasticity as well as the compressive strength of the concrete. Concrete cube of size 150 x 150 x 150 mm has been cured with varyingpercentage from 0 to 10%. Quantity of concrete cube is 24 which has been cured by above mentioned water percentage.
