Abstract

In recent years, there has been a growing interest in the use of supplementary cementitious materials and polymers to produce high-performance concrete. This paper shows the results of a study on the effect of metakaolin and polymer admixture on mechanical behaviour and durability properties such as permeability, carbonation and chloride penetration, chemical attack, rate of water absorption and the corrosion rate of the steel reinforcement in the concrete. The results indicated that replacing Portland limestone cement with 15% of metakaolin and additional 4% of styrene-butadiene rubber and 1% of polyvinyl acetate polymer by weight of cement improve the properties of concrete. In addition, microscopic structure and chemical composition analyses were performed to confirm the underlying mechanisms and the improvement of material properties for this mix design. This study is aiming to preserve the environment by reducing CO2 emissions in addition to the improvement of the sustainable high-performance concrete properties.
