Characteristics of Wall and Floor Tiles Using Waste Glass

Abstract:

Wall and floor tiles were fabricated by a dry pressing method using waste glass and clay. The properties of the tiles such as absorption, bulk density, porosity, compressive strength, and abrasion loss are investigated with the firing temperature and glass content. The properties are improved with increasing both the firing temperature and glass content. These properties, except the compressive strength, tend to be saturated from the glass contents of 70 wt % in the case of 1050
. The compressive strength shows the maximum values at the glass contents of 70 wt% and then which are decreased with increasing the glass contents. The optimal properties obtained in the tiles are the water absorption of about 0.9 %, the bulk density of about 2.3 g/cm3, 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
. These results are better than the properties of commercial clay tiles, due to easy melting and densification of glassy phase in the tiles.
