Production of Ceramic Tiles with Glass Waste and Kaolinitic Clay

The aim of this work is to obtain a ceramic tilesCeramic tiles with kaolinitic clayKaolinitic clay, argilliteArgillite, glassGlass mud, and bottle glass wastesGlass waste. The wastesWaste were initially benefited by drying, crushing, and sieving in a 200 mesh (0.074 mm) mesh and later incorporated in 20 wt.% in a typical kaolinite clayClay from Campos dos Goytacazes mixed with argilliteArgillite from Itu-SP in equal proportions. Specimens, with 8% moisture content, were obtained by uniaxial pressing at 35 MPa and fired at temperaturesTemperature of 1100 and 1125 °C. The physical and mechanical propertiesMechanical properties evaluated were: Apparent dry density, water absorption, linear shrinkage, and flexural rupture strength. The results show that both argilliteArgillite and glass wasteGlass waste act as a flux materialMaterials in a traditional ceramic formulation with clayClay as the base raw materialMaterials, making it possible to reach the specification of porcelain stoneware at temperaturesTemperature well below the usual industrial firing temperaturesTemperature.
