Effect of glass powder on the properties of clay mixture for porcelain stoneware tiles

Glass waste is nonbiodegradable and consumes valuable landfills. This study examined the utilization of discarded glass powder and clay to make porcelain stoneware walls and floor tiles. Raw materials were characterized by their mineral and chemical makeup. Glass compositions were fired at 1000-1100 °C for 1 hour. The effects of waste glass content on technological parameters such as linear shrinkage, water absorption, bulk density, and porosity were investigated. X-ray diffraction was used to do a microstructural investigation of the burned samples. Experiments show that waste glass can improve the physico-mechanical properties of materials with up to 35 wt% glass content at 1100°C. The final product (KC50CC15G35) at 1100 °C showed a weak absorbed water value (21.037%). The XRD spectra of KC50CC15G35 were measured in the range of 2Ɵ = 10° to 90°. KC50CC15G35 with COD 1011176 which is quartz low and the crystalline structure is hexagonal. The lattice parameters for KC50CC15G35 of a and c are 4.9 and 5.4 respectively. that the silicon (Si) has a higher peak than aluminum (Al).
