The waste generated from the industries motive environmental issues. For this reason the reuse of these wastes are often emphasised.Thus Marble dust powder (MDP) is one of the fast growing waste material which can be used in the concrete production industry to minimize material use and produce financial advantage. In this study, the marble dust powder passing through 90 micron sieve, has been utilized for determining the hardened properties of concrete .The hardened properties of concrete has been determined with the effect of different rate replacement of cement by MDP.In this examination work, MDP has replaced the Ordinary Portland Cement (OPC) at an increasing rate from 0 % to 20% by weight in M30 grade concrete. The motivation behind this investigation is to examine the behavior of concrete with the substitution of cement by MDP in various extents in concrete.
