Strength and Porosity of Cement Mortar Blended with Metakaolin

Abstract:

An experimental investigation was carried out to assess the effect of metakaolin (MK) on the compressive strength, flexural strength and porosity of cement mortar. The cement was partially substituted with MK at 0-30% replacement levels. The results show that the strengths and porosity of mortar containing up to 20% were superior to that of control (0% MK). The Balshin equation fits the experimental results of compressive strength and porosity of the specimens containing MK and there is a strong quantitative relationship between compressive strength and porosity of the specimens.
