Abstract
The conventional concrete has lost its usage in modern days as it does not serve the present needs. Hence in order to improve the properties of the concrete in the fresh and the hardened state, high performance concrete (HPC) is used. High performance concrete is a concrete that is produced by partially replacing concrete with improvised minerals. High performance concrete has been defined as the concrete that possess high workability, high strength, high dimensional stability, high durability, low permeability and resistance to chemical attack. This project deals with the effects of supplementary cementitious materials in concrete by incorporating fly ash and copper slag with a water binder ratio of 0.45. Here the conventional concrete is obtained by replacing fine aggregate with 60%, 70%, 80%, 90% copper slag and ordinary Portland cement is replaced with 20% of fly ash. From the experimental results, it is observed that high performance concrete exhibits improved compressive strength, split tensile strength and flexural strength when compared with the conventional mix.
