In the present study, the valorization potential of fly ash and waste glass was investigated for the production of CaO–Al2O3–-SiO2 glass-ceramics. Various fly ash-glass mixtures were uniaxially pressed and calcined at 900 οC, 1050 οC and 1100 οC for the production of glass-ceramics. Waste glass added as a sintering additive in order to reduce the glass melting and sintering temperature. A detailed investigation of the effect of glass addition and firing temperature on porosity, density, water absorption, and mechanical properties (compressive strength) was also carried out.The produced ceramics exhibited compressive strength up to 20 MPa, while the porosity values ranged from 5.6%-41.0% and the water absorption was below 2%. In all cases, when an increased amount of waste glass was used, porosity and water absorption values decreased, while an increase compressive strength was seen. In all cases sintering temperature affected the final properties of the produced ceramics. The produced glass-ceramics have acceptable values of physical properties i.e. porosity, density etc. and a moderate bending strength, and thus they are considered suitable for the building industry.
