Performance of calcined clays in mineral construction materials.

The potential of calcinated polymineral natural clay with low kaolinite content as an active additive to concrete is shown. In addition, it can be used to partially replace CaO in silicate autoclave-cured products, and to replace the sulfate component and, partially, cement in autoclaved cellular concrete.
