ABSTRACT
Concrete plays a vital role in the world of this paper is a part of experimental investigation to study the characteristic of concrete by using the combination of partial replacement of cement by dolomite and silica fume powder and partial replacement of fine aggregate by copper slag. The dolomite and silica fume is an anhydrous carbonate mineral made out of calcium magnesium carbonate and it is likewise used to portray as sedimentary carbonate shake. Dolomite and silica fume is also known as dolomite and silica fume. The dolomite and silica fume powder is the crushed mineral from dolomite and silica fume. Copper slag is a rough impacting coarseness made of granulated slag from metal refining procedures and it is likewise called as iron silicate. The replacement percentages of cement by dolomite and silica fume powder is 0%, 10% 20%, 30 & 40% and fine aggregate by copper slag is 20% by the weight of M20 grade concrete. The dolomite and silica fume powder and copper slag is mixed with natural cement and fine aggregate in the grade of M20. The concrete cubes and cylinders were casted with varying content of dolomite and silica fume powder and copper slag. The test specimens were cured and tested for compressive strength and split tensile strength in 7 days, 14 days, 28 days and 56 days for concrete.
