Nowadays Cement is major constituent material in construction industry and Lime and Silica producesthe Cement.Without these natural materials production of cement is very tedious task.Moreover the emission of Carbondioxide(CO2) is more in the production of Cement.It causes environmental pollution globally.Sand is also naturally available material ,it gives good strength to the concrete.But environmental degradation happened by scarcity of natural sand.The main motto of this work is to find alternate materials for partial replacement of Cement and sand in concrete to obtain required strength as well as to minimize degradation of natural materials.In this work Cement is partially replaced by Ground GranulatedBlast Furnace slag(GGBFS) and sand is Bottom Ash(BA) to achieve required compressive strength.By this investigation,replacement of 10% Cement and 10% sand in concrete with and without adding of admixture gave sufficient characterstic compressive strength of concrete for 28 days curing period.
