What does a pozzolan do in the concrete?
A. As the definition implies, a pozzolan combines with calcium hydroxide in the concrete to form calcium silicate hydrate, similar to that produced by hydration of portland cement. This adds to the strength, impermeability, and sulfate resistance, and reduces expansion from the alkalisilica reaction that might otherwise take place.

Mechanical Property Evaluation and Prediction of Cementing
One of the most commonly used pozzolans in the cement and concrete industry is metakaolin (MK), which is among the most abundant minerals. It can be acquired from the thermal decomposition of kaolinites. The behavior of clay minerals during calcination determines optimal activation of pozzolanic reactivity [ 7 ].

What is the difference between Pozzolan and Cement?
is that "pozzolan" is any material which, when combined with calcium hydroxide, exhibits cementitious properties; often used as an extender with Portland cements and "cement" is a powdered substance produced by firing calcium carbonate and clay that develops strong cohesive properties when mixed with water. The main ingredient of concrete.
