Effect of Metakaolin Content and Water/Binder Ratio on Strength and Durability Properties of Modified Cement Mortar

CODEN: JTEVAB

Abstract

The aim of this research was to examine the effects of metakaolin (MK) content and low water/binder (w/b) ratio on the basic performance and durability properties of cement mortar. The effects of various mix proportions on the flowability, consistency, water absorption, and mechanical properties of modified cement mortar were investigated. Also analyzed were the effects of MK content on the impermeability, frost resistance, and sulfate corrosion resistance of modified cement mortar when the w/b ratio was 0.31, according to the basic physical properties that were comprehensively considered. The internal microstructure of the modified cement mortar was analyzed by scanning electron microscopy. According to the results, 10 replacement levels were the optimum level of MK content in terms of strength and durability properties at a w/b ratio equaling 0.31. Compared with the control cement mortar, the modified cement mortar containing MK showed better development in strength and durability properties.
