A High performance concrete is something which demands much higher performance from concrete as compared to performance expected from routing concrete. Use of chemical admixtures reduces the water content, thereby reducing the porosity within the hydrated cement paste. Mineral admixtures also called as cement replacement material (CRM) such as fly ash, rice husk ash, Metakaolin, silica fume and additives such as metallic and non-metallic fibres are more commonly used in the development of High performance mixes, act as pozzolanic materials as well as fine fillers, thereby the microstructure of hardened cement matrix becomes denser and stronger. In this project, to replace the constituent materials by silica fume 0%, 10%, 20%, 30% and 40%, chemical admixtures and steel fibre and glass fibre 0%, 1%, 2%, 3% and 4% of additives also, it is proposed to use high performance concrete. Also High Performance concrete specimens with fiber and without fiber in size 150mmx150mmx150mm, cylinder of 150mmx300mm and prism of 100mmx100mmx500mm were cast and the strength tests were observed. An experimental result shows that the optimum strength attained on concrete with 30% of silica fume and 3% of steel and glass fibres. Where 40% of silica fume and 4% of steel and glass fibres result with decreased strength. HPC mixes 30% of silica fume and 3% of steel and glass fibres have better resist against Hcl and MgSo4 compared to conventional concrete.
