Cement Concrete is most widely used material for various constructions. When compared with steel, concrete is most widely used in construction. But concrete has some of the drawbacks like low tensile strength, less ductility, heavy weight, high shrinkage and high permeability. To overcome these drawbacks many researchers all over the world are actively involved in improving the properties of the concrete according to their applications. As a part of my research work an attempt is made to study the strength & durability of steel fibre reinforced Metakaolin blended concrete, when it is exposed to certain types of chemicals. Metakaolin is a thermally structured, ultra fine pozzolona, which replaces industrial byproducts such as silica fume,  fly ash, etc.,. This paper presents experimental investigations carried out to evaluate the strength and the durability in terms of Chemical Resistance and weight loss of steel fibre reinforced concrete with and without Metakaolin for concrete of M50 grade. Concrete cubes are made with partial replacement of ordinary Portland cement by Metakaolin. Water to cementitious material ratio used is 0.55. The optimized dosage of super plasticizer is noticed as 1 % weight of binding material. In this investigation an attempt is made with chemicals like H2SO4 and HCl. Crimped Steel fibres with 80 as aspect ratio at 0, 0.5%, 1.0% and 1.5% of volume of concrete are used. The results show that the percentage of weight loss is reduced and compressive strength is increased in the case of Steel fibre reinforced concrete and concrete containing 10 % Metakaolin replaced concrete when compared to the normal concrete. Also the less percentage weight loss is noticed in the case of HCl and severe in the case of H2SO4.
