Abstract: This paper report the characterisation and study of physico-chemical stability of ceramic floor tile. Ceramics obtained at different temperature (750, 850 and 950°C) were produced using a bauxite red mud of Ngaoundal and CRT waste glass mixture. Six samples were prepared by varying the mass of glass powder according to a percentage weight ranging from 0 to 40 %. The experiment carried out consisted of characterizing both the raw materials and the ceramics produced by chemical analysis, mineralogical analysis (X-ray diffraction, infrared spectroscopy, scanning electron microscopy, distribution size, thermal analysis, linear shrinkage, percentage of water absorbed and flexural strength. The results obtained showed that linear shrinkage slightly increases (0,7 to 1,5 %) as the mass of the glass powder added increases while the percentage of the absorbed water decreases (18,5 to 10,8 %) leading to a decrease in porosity. Flexural strength increases from 4 to 10,8 MPa when the mass percentage of the additive and temperature increases, this being related to the density of the product due to the formation of a vitrous phase brought by the additive. As a result, addition of glass powder into the red mud bauxite studied allowed the production of ceramics with ameliorated properties.

Key words: Red mud bauxite, CRT waste glass, firing temperature, mechanical and chemical properties.
