Strength and microstructure of mortar with sand substitutes

Jeyaprabha Balasubramanian, Elangovan Gopal, Prakash Periakaruppan

Abstract

The strength and microstructure of mortars incorporating manufactured sand (MS) and various levels of granite powder (GP) as substitutes for river sand (RS) are considered in the paper. The optimum RS substitution by GP is 15 % by mass for the maximum compressive and splitting tensile strength. Strength properties of mortars containing MS are better when compared to RS and GP mortars, irrespective of the curing period. The thermal analysis, microstructural analysis, and mineralogical analysis are conducted on MS and GP mortars using TGA, SEM, XRD and FT-IR techniques.
