Metakaolin

MetaCem grades of calcined clays are reactive alumino-silicate pozzolans formed by calcining very pure hydrous chinaclay. Chemically, MetaCem combines with calcium hydroxide to form calcium silicate and calcium aluminate hydrates. Unlike other natural pozzolan

Frequently Asked Questions

Common questions about Metakaolin in construction applications

Metakaolin (MetaCem) is produced by calcining very pure hydrous chinaclay. It is water-processed to remove unreactive impurities, resulting in almost 100% reactive alumino-silicate pozzolan with ultrafine particle size significantly smaller than cement.

MetaCem combines with calcium hydroxide (formed during cement hydration) to produce additional calcium silicate and aluminate hydrates, improving compressive strength, reducing water penetration, lime leaching, and enhancing surface finish.

Yes. IS 456:2000 recommends the use of Metakaolin as a Mineral Admixture in concrete, recognising its significant contribution to concrete durability and strength.

Yes. MetaCem is a thermally structured, ultrafine pozzolan designed to replace industrial by-products such as silica fume and microsilica, offering equivalent or superior performance with a more environmentally friendly profile.

It is used in high-performance concrete, ready-mix concrete, precast concrete products, white concrete, repair mortars and micro-concrete, grouts and injection mortars, and self-compacting concrete.

MetaCem is produced from natural chinaclay by calcination — a clean process with no industrial by-products involved — making it a more sustainable and environment-friendly pozzolan compared to silica fume.
