ABSTRACT
Wall and floor tiles were fabricated by a dry pressing method using waste glass and clay. The physical properties of the tiles such as absorption, bulk density, porosity, compressive strength, and abrasion loss are investigated with the firing temperature and glass contents. The physical properties are improved with increasing the firing temperature and glass contents. The composition containing the glass of $70 wt%$ and fired at $1050^{circ}C$ for 2 h has the good properties. The optimal properties obtained in the tiles are the water absorprion of about $0.9%$, the bulk density of about $2.3;g/cm^3$, the apparent porosity of about $2.1 %$, the compressive strength of about 210 MPa, and the abrasion loss of about 0.022 g, when the composition containing the glass of $70;wt%$ is fired at $1050^{circ}C$. The physical proper1ies of tiles fabricated were enhanced compared to the commercial clay tiles, due to easy melting and densification of glassy phase during the firing process.
