How much clay is used to make cement? Clay is a compact, impermeable sedimentary rock that becomes plastic, malleable, and more or less thixotropic if there is water present. Its physico-chemical properties vary in accordance with its fineness of grain. Consisting basically of aluminosilicate, it is one of the raw materials from which cement ...
