Engineering Effects of Metakaolin on Concrete – A Review Paper

Abstract

Metakaolin is manufactured by controlled process of thermal treatment of kaolin. It can be replaced instead of cement in concrete which possess excellent pozzolanic properties. Generally cementitious material that are used in concrete are flyash, ground granulated blast furnace and silica fume. This can save energy, conserve resources and technical benefits to engineers. To reduce the environmental damage the solution has by far been the use of supplementary cement materials. Which could, not only decrease the amount of cement used in concrete but also increase the overall behaviour of the concrete. The different percentage replacement of metakaolin in concrete plays an important role which decides the mechanical strength properties.
