AbstractA 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
Highperformance concrete (HPC) is a new type of concrete that conforms to a set of properties like strength, water and chloride permeability and resistance to alkali silica reaction that leads to long service life in severe environments.

Furthermore, mix design of highperformance concrete is more complicated because it involves many variables and includes various mineral and chemical admixtures. To date, the construction industry had to depend on a relatively few human experts to give recommendations in solving high performance concrete mix design
High Performance concrete works out to be economical, even though its initial cost is higher than that of conventional concrete because the use of High Performance concrete in construction enhances the service life of the structure and the structure suffers less damage which would reduce overall costs.
Today, high performance and high strength concrete has been started to be produced with the use of chemical and mineral additives in modern constructions, industry constructions, tunnels or structures built for the purpose of private services. The behavior of concrete under the effect of high temperature should be known well (Zhai et al., 2014;
