This paper presents results from experimental investigation carried out to study the hardened properties of M25 grade concrete by partial replacement of fine aggregate with Copper Slag(CS) as well as Tile Powder(TP) and to compare the same with that of control concrete by conducting various tests. The strength characteristics of CS incorporated concrete was found out by replacement of 0%, 30%, 35%, 40%,45% and 50 % in Fine Aggregate, Out of these 40% replacement gives highest compression strength at 28 days. The strength characteristics of TP incorporated concrete was found out by replacement of 0%, 10%, 15%, 20% ,25% and 30 % in Fine Aggregate, Out of these 20% replacement gives highest compression strength at 28 days. The Strength of Concrete with varying replacement of fine aggregate from 0%, 30%, 35%, 40%, 45% and 50% was investigated. Again in the above replacements, combinations of TP & CS by 50% TP & 50% CS and 60% TP & 40% CS was studied, Out of these 40% replacement of 50% CS and 50% TP gives highest compression strength at 28 days. Various tests were conducted for above obtained optimum percentages ,such as compressive strength, split tensile strength , modulus of elasticity and flexural strength. Sorptivity test is also conducted for durability check.
