An experimental study on partial replacement of cement by silica fume and steel slag

Abstract

In this industrious world due to pollution, the amount of emission of co ₂ has to be reduced. And so the amount of CO₂ which is being used as main binding materials in construction industry can be replaced by its alternative material. One of the materials is steel slag and silica fume which are by-products from steel industry. In this experimental study, we are partially replacing cement by silica fume and again cement by st eel slag with 2.5%, 5%, 7.5%&10%. Mechanical properties are being studied to select which material is best and suited for cement in construction industry. The concrete blocks were prepared and tested and the results were discussed.
