The objective of this study was to use the waste in the construction ceramic, because it does not degrade in nature due to its chemical composition and a contribution to the reduction of this waste in landfills and visual pollution. Thus, a sample of this material was selected so that their characteristics regarding chemical composition, X-ray diffraction, differential thermal analysis and thermogravimetric analysis could be studied. Mixtures were prepared containing 0%, 5%, 10%, 15% and 20% by weight of waste, and sintered at a temperature of 850 ° C. After water absorption, linear shrinkage and mechanical strength tests were performed. The physical-mechanical properties were determined according to the% of waste added. The results revealed a series of phase transformations during sintering. Moreover, the sintered bodies containing residual construction are likely use in red ceramic, contributing to waste minimization and self-sustained development. |
