    Abstract: Concrete is one of the important construction material used in the world of all engineering works
including the infrastructure development proved that, it is a cheap material and its constituents are widely
available in nature. Due to wide spread usage and fast infrastructure development in all over the world, there
is shortage of cements. In this study, cement will replaced by coal ash and M-sand powder accordingly in the
range of 0, 5, 10 and 15% in M-25 grade concrete.
