Now a days the production of cement is highly coastly and significantly affects the environment. the CO2 has increased manifold over the last decade or so leading to global warming .thus it is the need of the how to contro the usage of cement so that its production can be reduced optimal usage the present study has been done to find the optimal usage industrial by products fly ash, silicafume, limesludge to be as substitutes of cement Fly ash, a byproduct from the thermal power plant and it is a pozzolanic material. Silica fume as very fine non crystalline silica produced in blast furnace as by product of the production of elemental silicon or alloys containing silicon .Lime sludge is generated from paper, acetylene, sugar, fertilizer, sodium chromate and soda ash industries Attempts have been made to study the properties of self-compacted concrete and to investigate properties of fly ash, silica fume, lime sludg and its suitability of those properties to enable them to be used as partial replacement materials for cement in concrete Experimental investigation on strength aspects like compressive, flexural, and split tensile strengths of self-compacting concrete (SCC) containing different levels of flyash, silica fumes, lime sludge, and workability tests for different mineral admixtures (slump, L –box, V-funnel and T50 ) are carried out .the methodology adopted is that mineral fly ash is replaced by ((5%,10%,15%,20%,25%,30%), silica fume (5%,10%,15%,20%,25%,30%), lime sludge (5%,10%,15%,20%, 25%,30%) in cement and performance is measured and compared. Hardned tests carried out by two different combinations of these three pozzolanic materials 1.(flyash+silica fume+limesludge) is replaced by(25%+5%+0%, 20%+5%+5%, 15%+5%+10%, 10%+5%+15%) in cement and performance is measured. 2. (silica fume+fly ash) is replaced by (2.5 %S+5%F, 5%S+10%F , 7.5%S+15%F, 10%S+20%F, 12%S+15%F ) in cement and performance is measured.
