METAKAOLIN IN CONCRETE – BENEFICIAL IMPACT ON

2018-7-11  The hydration of normal Portland cement produces calcium hydroxide. Metakaolin will react with the calcium hydroxide, decreasing the amount of this product in the microstructure and, in addition, producing more calcium silicate hydrates and calcium aluminosilicate hydrate via pozzolanic reaction. Thus, the partial replacement of cement with metakaolin will increase the performance of the concrete.
