Product Description

Pozzuolan is a calcined clay additive which is used to provide increased strength to traditional mortars by converting aerial lime into hydraulic lime. When used in mortars containing lime, Pozzuolan reacts with the free lime (Ca (OH)2) forming beneficial calcium silicate and calcium aluminate cementitious products. Pozzuolan can also be used in cement based products to enhance the performance of ordinary Portland cement mixes.
