Mechanical and thermal properties of cockles shell cementing material

Abstract

Mortar of ordinary Portland cement was blended with cockles shellpowder at different weight ratios to investigate the effect of powderadmixture on their strength and thermal conductivity. Results showedthat addition of cockles shell powder at 50% of mortar weightimproves hardness and compressive strength notably and reduces thethermal conductivity of the end product. Results suggest thepossibility to incorporate cockles shell powders as constituents incement mortars for construction and plastering applications.
