Effect of incorporation of self healing admixture (SHA) on physical and mechanical properties of mortars

초록

This paper presents the results of experimental investigation carried out to assess the effect of crystalline admixture-a self healing admixture (SHA) on the physical and mechanical properties of mortars. Crystalline admixture (CA) totaling 3% by weight of cement was added into cements and lime mortars. The porosity and water absorption capacity was significantly reduced for mortars with SHA. An overall improvement in compressive and flexural strength was observed with the inclusion of SHA. An increase in modulus of elasticity and reduction in brittleness factor was observed for mortars with SHA. Effect of sand gradation was also found prominent on physical and mechanical properties of mortars.
