%X In the present study the preparation of glass-ceramic composite materials containing lime-free clay and industrial waste: steel cooling refuse from metallurgical plant, waste glass from waste fibre production, aluminium scrap metal processing waste were investigated. Taking into account the thermal properties and chemical composition of raw materials, various waste containing glass-ceramics composites were prepared by powder technology. Dense glass-ceramic composite materials (bulk density 2.52 - 3.24 g/cm3; water uptake 0.95 - 5.5 %) were produced in sintering temperature range from 1140¡ãC to 118¡ãC. Considering the low water uptake and values of mechanical properties determined (the modulus of elasticity E = (1150 - 1300) ¡À 200 MPa and the compressive strength ¦Ò* = (50,6 - 89,9) ¡À 15,0 MPa), the produced composite materials could be regarded as corresponding to the group BI of the standard LVS EN 176:1991 "Pressed ceramic tiles with the low water uptake" (E<3 %) and to the criteria for building ceramics according to LVS 163-3:1999. Potential application is the production of "unglazed ceramic tiles for road pavement and exterior walls from stone ceramics" (code - 690790910).
