Metakaolin inclusion: Effect on mechanical properties of concrete

Nowadays there is an increasing trend of utilization of waste/non - conventional materials in cement and concrete matrices. These materials are often used as a part replacement of cement reducing the cost of construction and help to overcome the deficiencies associated with the use of Ordinary Portland Ceme nt (OPC) alone. Also, these materials generally impro ve the strength of cement/concrete matrices and other quality aspects. Metakaolin is a waste/non - conventional material which can be utilized beneficially in the construction industry. Metakaolin inclusion increases the compressive, tensile, flexural and bend strength and modulus of elasticity of concrete considerably; however, the work ability is slightly compromised. This paper presents the review of investigations carried out to find the suitability of metakaolin in production of concrete.
