Review on the Durability Characteristics of Metakaolin in Concrete – A Review Paper

Abstract

Silica fume (SF) and Metakaolin are cementitious materials used as admixtures to produce high strength concrete and to decrease the permeability. Silica fume combined with ordinary Portland cement used to prepare durable concrete. Places where poor curing concrete structures such as sea shores, underground structures undergo severe loss of compressive strength and permeability interconnected with durability, using of Metakaolin and Silica fume in an optimum proportion modifies the properties of concrete. To test the strength properties, Compressive strength and split tensile test were carried out and to check the durability properties of concrete Sorptivity test were conducted. The test results shows that the two admixtures Silica fume and Metakaolin when used at an optimum mix ratio tend to improve the strength and durability of concrete when comparing with conventional concrete.
