Literature Review on partial replacement of cement by fly ash on strength of concrete

The objective of this paper is to explore the feasibility and effect of replacement of coarse natural aggregates with blast furnace slag and partial replacement of cement by silica fume and fly ash in different percentage proportions. This will help in conserving the natural resources and keeping ecological balance to fulfill present demand of construction material in infrastructure development sector which is increasing at alarming rate. Therefore it is required to reduce the use of natural aggregates and cement to meet the future demand which will enhance the utility of waste materials and at the same time minimize the demand for natural aggregates and cement.
