Experimental Study on the Properties of Concrete with Replacement of Cement by Quarry Sludge

Abstract

Quarry sludge is a residue which shows certain chemical properties similar to cement that is obtained from rock crushing units. Like every industrial waste, quarry sludge also causes environmental hazards which urges to think of an outcome of utilizing it in an efficient manner. Currently, there are many researches to use supplementary cementing materials as cement replacement partially to accomplish more strength. This experimental program encompasses 0%, 5%, 10%, 15% and 20% of cement replaced by quarry sludge for M30 grade concrete for studying the strength properties and durability properties. This study also includes Scanning Electron Microscopy and X-Ray Diffraction. Results showed up 20% of partial replacement of quarry sludge improves strength properties of concrete.
