Experimental Study on High Performance Concrete by using Partial Replacement of Copper Slag and Fly Ash

The conventional concrete has lost its usage nowadays as it does not set out the present need. The term ‘High Performance’ is because of the essential usage, materials and proportions of this concrete are specifically chosen for properties such as high workability, high density and low permeability. The main objective of this study is to deal with the effects of cementitious materials in High Performance Concrete HPC for mix design of M40 grade concrete. Hence, copper slag which is the industrial by product is used as a partial replacement of fine aggregate by 0 , 15 , 30 , 45 , 60 and 75 with 20 of fly ash by the volume of cement with water cement ratio 0.36. Super plasticizer conplast SP430 is used as chemical admixture at the rate of 1.2 of cement which improves the workability. From this experimental study, so far the utilization of copper slag and fly ash observed with gradual improvement in mechanical properties such as compressive, split tensile and flexural strength in HPC. By evaluating the optimum percentage of copper slag, J. Grijasri | U. Karunya | A.
