- Since the infrastructure is developing tremendously day by day, the use of cement is highly used. India is developing as a major hub for service industry, automobile industry and for which the infrastructure development plays an important role. So the necessity of high strength concrete is increasing. In all construction work concrete is mostly used and it is costly which governs the total cost of the project. Since cement emits carbon dioxide both at the time of its production and consumption, we need to replace cement with other material to enhance its property. Some of the most commonly used material to enhance the property of concrete are metakaolin, silica fumes, fly ash etc. Cement is replaced to reduce its consumption to avoid the environmental pollution and save nature. It makes the cost efficient and enhances the compressibility and durability of MK concrete. Metakaolin is a unique in its very own form as it is not the by-product of an industrial process nor it is entirely natural. It is derived from naturally occurring minerals, and is manufactured specifically for cementing applications. Metakaolin has pozzolanic properties bringing positive effects on resulting properties of concrete. Metakaolin is manufactured by cretaceous clay which is kaolin. This clay is usually found at the bank of certain rivers. The metakaolin is manufactured by heating cretaceous clay under the temperature of 500 ? 800 0C for 3-5 hours by the process of calcination. This results in change of kaolin into metakaolin. The resultant metakaolin has high pozzolanic characters and it increases durability and stability (mainly physical properties) when partially replaced with Ordinary Portland Cement. This Project deals the study of effect of Calcined kaolinite clay when partially replaced with cement with different percentage (10%, 15%, 20%and 25%).The compressibility and durability of the concrete is studied. It was found that the maximum compressive strength was at 15%.
