Abstract:
The work aims to evaluate the influence of different levels of residue on the physical and mechanical properties of a typical composition of red ceramic, which is marketed in Campos dos Goytacazes, Rio de Janeiro. The residue comes from the first stage of glass manufacturing in a conventional tempering process. Ceramic specimens were prepared with 0, 5, 10 and 20% residue incorporations. The samples were obtained by extrusion, dried and fired at 800, 900, 1000 ° C in a laboratory oven. Analyzes of the raw materials were carried out, among which the morphological, physical and chemical ones can be highlighted, and afterwards tests were carried out on the fired ceramic specimen. The firing properties obtained were dry bulk density, water absorption, linear firing shrinkage. The results obtained demonstrated that both the increase in the glass content and the increase in the temperature had positive effects on the studied properties, and, in addition to that, the glass acted in order to lower the appropriate firing temperature
