Review of application of plain and calcined bentonite as a cement blending material in concrete and mortar

Abstract

The construction industry been growing at a rate of 5 to 6% in last 05 years. Cement is the major and second most expensive materials amongst all construction materials. Also production of cement very high amounts of CO2 emissions. Hence replacing cement without negatively affecting strength and durability properties cloud be an effective approach to solve the above issues. Out of the many materials used for cement blending bentonite possesses a potential to partially replace cement in production of concrete and mortar effectively.

Bentonite is a clay mineral which finds its use in variety of industrial applications. Here an attempt has been made to summarize the experimental results by many of the researchers to partially replace cement with plain and calcined bentonite. In the literature the concrete and mortars samples were experimentally tested for strength, workability and various durability properties
