Clay building / Building chemistry / Abrasives

Ground clays with their natural ochre and brown-grey colour shades are the basis for plasters, filling of timber framings, elements and mortar. In building material and its chemical com- ponents that are made from plaster, our clays act as active fillers and improve such properties as elasticity and heat resistance. Fat clays are suitable for ceramic-bound abrasives.
