Effects of the Basaltic Tuff Additions on the Properties, Structure and Phase Composition of the Ceramic Tiles for Interior Wall Facing

Basaltic tuffs are indispensable associated rocks during extraction of basalts, which are formed from igneous basalt fragments, cemented and compacted by volcanic glass and ash. The chemical and mineralogical composition, behaviour during heating and particle size of tuffs compared with basalts are studied. Physical and chemical properties, the structure and phase composition of the samples of tiles using tuffs are defined. The possibility of sharing basalts and tuffs in the composition of masses for the tiles of interior wall facing in order to improve the mechanical strength of finished products and reduce their material capacity is established.
