ABSTRACT: This paper aims to highlight the impact of using metakaolin on engineering properties of structural concrete. Metakaolin solved the pollution problem resulting from concrete industry. Metakaolin produced by Calcining Kaolinite at high temperature to get pozzolanic material which can be used in concrete mixes. This paper aims to investigate and evaluate the durability of Concrete containing metakaolin. The physical and chemical characteristics of metakaolin Concrete will be examined. Durability tests of metakaolin Concrete involve chloride penetration, water permeability, abrasion, water absorption and concrete resistance tests. Behavior of metakaolin Concrete under elevated temperature will be also studied. This paper demonstrates that replaced cement in Concrete with metakaolin enhances durability and mechanical properties of concrete included different type of cement under various type of curing, Metakaolin Concrete has a positive effect on compressive strength after exposure to escalated at different temperature.
