Supplementary cementing materials (SCMs) are additives used to modify or enhance the properties of cement. These materials can either occur naturally or be generated as byproducts of industrial processes. Wide range of SCM’s is available in the market. Each being made available at a economical production and efficient utilization in the construction industry. Metakaolin is one among them, produced by calcining kaolin clay at high temperatures. It has the unique ability to generate calcium silicate hydrate gel due to the reaction between the calcium hydroxide and water. C-S-H produced is the primary binder in cementitious materials. The resulting C-S-H gel fills the voids in the concrete matrix, improving its durability and strength. In this study, the authors provide an overview of their experimental work that involved partially replacing cement with metakaolin in concrete. The report on various concrete samples with different levels of substitution has been represented in this article. It is found that the inclusion of metakaolin into the concrete mix has influenced the workability in fresh state along with altering the strength parameters in the hardened state.
