ENHANCEMENT OF SUGAR AND ALCOHOL INDUSTRY WASTES IN CLAY MASSES

Abstract

This work had the objective of realize the incorporation of wastes – soot and water from sugar cane washes soot and sugar cane (clay) in ceramic formulations. It was carried out chemical and physical characterization of the wastes by X-ray fluorescence method, laser granulometry and X-ray diffraction of the clay. It was analyzed increments of the wastes (0, 5, 10 and 15%). The samples were compressed and burned at different temperatures (700, 800 and 900 °C). The following properties were determined: Atterberg limits, loss by fire, linear shrinkage and dry-firing, water absorption and color of burning. The proposed clay masses presented potential of application to the production of red ceramics and the color of burning related to the high levels of Fe2O3 tended to dark red. It can be observed changes in color (black spots) and deformations to the masses with increment of soot. Key words: Clay. Industrial Waste. Red Ceramic. Physical Properties. Burning. Recycling.
