MetaCem 85C – High Reactivity Metakaolin – HRM is a scientifically processed reactive allumino silicate pozzolan formed by calcining purified clay in an externally fired rotary kiln. Metakaolin react with Calcium Hydroxide at ordinary temperature to form Calcium Silica & Calcium Alluminate Hydrates, unlike other natural pozzolan, MetaCem is a water process to remove unreactive impurities, producing excellent reactive material. A thermally structured ultrafine pozzolan replaces industrial by product such as Silica Fume - Micro Silica, one of the widely used mineral admixtures, without compromising the end result. The particle size of MetaCem is significantly smaller than cement & blending leads to enhance the property of Portland cement: |
