Kaolin Clay for Cement Industry

In cement applications, kaolin clay is commonly used as a supplementary cementitious material (SCM) or as a pozzolan. The specific type of kaolin used in cement applications is typically Calcined Kaolin and Meta Kaolin.


Meta Kaolin

Meta kaolin exhibits pozzolanic properties, meaning it reacts with calcium hydroxide in the presence of water to form additional cementitious compounds. This reaction contributes to the strength, durability, and other desirable properties of cementitious materials. By replacing a portion of the cement with metakaolin, the overall heat generation during the hydration process is reduced, minimising the risk of thermal cracking and improving the long-term durability of the concrete.
