Abstract Scope |
The kaolinitic clays are known by their refractory behavior with elevated porosity after the firing stage. In the present work, the incorporation of up to 30 wt% of a sludge waste from the polishing of cutted glass plates into a typical kaolinitic clay body was evaluated. The raw materials were characterized by XRD, XRF, particle size distribution and DTA/TGA techniques. Specimens were extruded and fired at temperatures ranging from 800 to 1100°C. The technological properties were evaluated in terms of water absorption, linear shrinkage, and flexural rupture strength. The microstructure of the ceramics was evaluated by SEM. The results indicated that the waste incorporation improved both the ceramic water absorption and the mechanical strength. Finally, this work indicated that clayey rustic floor tiles production is a viable and technically advantageous alternative for recycling this type of waste, also bringing real benefits to the quality of ceramics. |
