Given paper presents the results of an investigation on reversibility of glass-ceramic materials based on various combinations of inorganic industrial waste - steel cooling refuse, etching refuse and alumina containing waste. In order to investigate the sintering capability of different waste types, the thermal behaviour (by DTA), mineralogical composition (by XRD) and chemical composition of testing solutions after leaching tests of waste were analysed. The main chemical elements - Al, Fe, Ca, Mg, Cu and Pb were determined. The glass-ceramic materials with properties corresponding to building ceramics (bulk density 2,3 – 2,9 g/cm3, water uptake 0,15 – 0,6 %) prepared from wastes mentioned above and clay in different ratio were obtained. Chemical durability of new composite materials was determined using four test-methods. The presence of Cu, Al, Fe, Ca and Zn was detected after the treatment of samples with acidic, alkaline and water solutions. After the treatment in acidic test-solutions the changes of microstructure and decrease of Fe, Cu, and Mg concentrations in materials microstructure were observed. According to obtained results, new glass-ceramic composite materials have properties corresponding to building materials.
