Different types of glass and glass-ceramics were made using industrial wastes of fly ash, concrete sludge, and glass cullet. Considering the production of wollastonite crystal, the mixing ratios of these wastes were determined on the basis of the phase equilibrium diagram of CaO-Al_2O_3-SiO_2. The glass-ceramics with wollastonite crystal containing a small amount of CaO showed better mechanical and chemical properties.
