Glass-ceramics functional properties for building application

Dense glass-ceramic composite materials (bulk density 2.5 – 2.7 g/cm3; water uptake 0.9 – 5.5 %) were produced from waste glass, steel cooling refuse, aluminium scrap metal processing waste and carbonate less clay. The functional properties of novel materials as well as environmental impact were detected. Some mechanical characteristics as ultimate stress (*) of these materials were determined by four point bending, results are comparable to building ceramics. The correlation between structure, composition and properties of sintered glass-ceramic materials as a function of sintering temperature rate was developed. Ecotoxicity of glass-ceramic containing industrial waste was determined by Daphnia magna ecotoxicity test (LVS EN ISO 6341:1996). LC50 concentrations were detected
