The role our kaolin plays in your cement mix
Pozzolanic Reactivity
Metakaolin reacts with calcium hydroxide to form additional binding compounds.
Strength & Durability
Improves compressive strength and reduces permeability in concrete.
Consistent Raw Material Chemistry
Stable silica and alumina levels support predictable clinker chemistry.
Reduced Clinker Factor
Supports lower clinker content in blended cement without compromising performance.
Sree Sai CemPozz Metakaolin
Sree Sai CemPozz is a calcined kaolin (metakaolin) developed as a pozzolanic raw material for blended cement and high-performance concrete admixtures. Its controlled reactivity improves strength development, reduces permeability and enhances long-term durability.
