Ceramic Brick with High Water Retentivity Prepared from Ceramic Waste and by Products

Abstract:

Article Preview

Many kinds of industrial waste were examined as potential constituents of ceramic bricks or tiles. The basic physical properties of these materials were measured, such as sintering temperature, water absorption, porosity, density, color, chemical stability and bending strength. Several kinds of sintered ceramics containing large amounts of waste materials were obtained by adjusting the amount of the waste materials added to the ceramics. These were fired at temperatures lower than 1000°C. A lowering of firing temperature results in a reduction of discharge of CO2 on the production process. Ceramic brick with high water retention is expected to mitigate the heatisland phenomenon by the latent heat of evaporation. Porous ceramics were prepared using industrial waste, burned ash and recycled roofing tile as raw materials. The permeability, water retentivity, water absorption, and other properties of the porous recycled ceramics were investigated. The pF value of the ceramics was measured as an indicator of water retentivity. An appropriate method of characterizing water retentive ceramic materials was also discussed based on results of fundamental examination of the ceramics under practical conditions.
