Overview
Metakaolin is kaolin clay calcined under controlled conditions. It reacts quickly with the calcium hydroxide released by cement, producing extra binding compounds. The result is higher strength, lower permeability and better resistance to chlorides, sulphates and alkali-silica reaction.
Its light colour makes it a good choice for architectural and white concrete, mortars and grouts.
