Utilization of Industrial Waste as an Additive to a Ceramic Wall Tiles Mizture
Sodium silicate, (commercially known as water glass), which is necessary for many industries such as paper and detergents, results an industrial waste, from its production. This waste includes both Sodium and Silica, that can be utilized in a ceramic mixture, due to their fluxing effect, for saving energy and getting rid of environmentally annoying waste. In the present work, the dried sludge was finely ground to form a powder additive to a mixture of Egyptian raw materials used in the manufacture of ceramic wall tiles. It replaced 5, 10, 15 and 20 % of the mixture by weight. The experimental program includes chemical assessment of both mixture and sludge through an XRF and XRD. The firing program of 2 stages was applied for the dry pressed samples at 1000, 1050, 1100 and 1150oC at a heating rate of 999oC/h till 400oC. Green compressive strength, firing linear and volumetric shrinkage, weight loss, water absorption, bulk density, apparent porosity and compressive strength were all measured and investigated as vitrification parameters and some of them were compared to both ISO and Egyptian Standards. The SEM was accompanied by a microanalysis (EDAX) on spotting at the figures, in order to recognize the existing phases and minerals.
