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.

폐유리와 점토를 이용하여 일축 가압 성형법으로 타익을 제조하였다. 유리함량, 소성온도 및 소성시간에 따른 타일의 흡수율, 밀도, 겉보기 기공률, 압축강도, 마모감량 등을 고찰하였다. 소성온도 및 유리함량이 증가함에 따라 타일의 특성은 향상되었다. 폐유리를 $70wt.\%$ 사용하고 $1,050^{circ}C$에서 소성한 타일이 가장 우수한 특성을 나타내었으며, 이 때의 흡수율, 밀도, 겉보기 기공률, 압축강도, 마모감량은 각각 $0.9\%,\;2.3g/cm^3,\;2.1\%$, 210 MPa, 0.022g이었다. 이는 유리상의 혈성에 의잔 결과로서 타일의 기공 감소 및 치밀화에 기여하기 때문이다. 제조된 타일의 특성은 상용화되고 있는 일반 자기질 타일과 비교하여 우수한 특성을 나타내고 있으며, 바닥 및 내$\cdot$외벽용 무유타일로 적용 가능할 것이다.
