Meta kaolin
[Al₂Si₂O₇]
A highly reactive aluminosilicate produced by controlled calcination of kaolin clay, used as a high-performance pozzolanic additive in cement, concrete and construction materials.
A High-Performance Pozzolan from Kaolin
Metakaolin is a highly reactive aluminosilicate produced through the controlled calcination of purified kaolin clay. Precise thermal treatment transforms kaolin into an amorphous mineral phase with strong pozzolanic reactivity while maintaining the fine particle characteristics required for consistent performance. Primarily used as a supplementary cementitious material, metakaolin reacts with calcium hydroxide generated during cement hydration to form additional cementitious compounds. This can improve strength, reduce permeability and enhance the durability of concrete and mortar. Our metakaolin powder is suitable for construction formulations requiring controlled mineral quality and reliable performance.
