Influence of the Dry Bulk Density on the Properties of Ceramic Paver Body

Article Preview

Abstract:

This work has as its objective to evaluate the influence of the dry bulk density in precursor body formulations developed to fabricate ceramic paver. Cylindrical specimens were uniaxial press-molded into two dry bulk density ranges, 1.99-2.05 g/cm3 and 2.18-2.23 g/cm3, from three formulations elaborated with clays, argillite and grog and then fired at 850 and 950oC. The evaluated properties were: water absorption and uniaxial compression strength. The results indicated that the packing during the forming stage is an important technological parameter that significantly influences the evaluated properties.
