Concrete is the most commonly used material for construction. Supplementary cementitious materials are finely ground solid materials that are used to replace a portion of the cement in a concrete mixture. These supplementary materials may be naturally occurring, manufactured or manmade waste. Metakaolin is a dehydroxylated aluminium silicate. From the recent research works using Metakaolin, it is evident that it is a very effective pozzolanic material and it effectively enhances the strength parameters of concrete. This paper presents the results of an investigation on the use of metakaolin (MK) as a supplementary cementing material to improve the performance of concrete. Three MK replacement levels are employed in the study: 10%, 15% and 20% by weight of the Portland cement used. The performance characteristics of the concretes are evaluated by measuring compressive and splitting tensile strengths, bond stress. The results revealed that the inclusion of MK remarkably increases the strength properties of concrete depending mainly on the replacement level of MK.
