Utilization of industrial waste materials and other supplementary materials in concrete compensates the lack of natural resources, solving the disposal problem of waste and to find alternative technique to safeguard the nature. Also it can be used to enhance the mechanical and durability properties of the concrete. There are a number of supplementary materials such as silica fume (SF), Ground Granulated Blast Furnace Slag (GGBFS), Fly Ash (FA), Rice Husk Ash (RHA) and more used as partial replacement of cement. This paper carries out a thorough assessment about the addition of SF and GGBFS, which can be adequately utilized in concrete as cement substitution. For that water cement ratio was fixed as 0.55 and the replacement level is from 5% to 20%. Totally nine mix were prepared in the range of 0 to 25 % of SF and GGBFS in binary and ternary system. Different properties were studied to identify optimum level of replacement such as physical properties, chemical properties of materials and mechanical properties.
