Potencialidades da produção de adoquim com a massa utilizada na fabricação de telha prensada

Abstract

This survey aimed to assess potentialities from the ceramics used in the manufacturing of the pressed tile into production a ceramic floor- adoquin. The raw material obtained and manufactured from the red-ceramic industry in region of Teresina was characterized by x-ray fluorescence, x-ray diffraction, thermogravimetric analysis and plasticity. It was prepared bodies of test with dimensions 250x125x80 mm by press. Then they were synthetized in temperature at 950 °C, 1050 °C and 1150 °C, and the technological properties were: linear retraction, loss to the fire, water absorption, apparent porosity, apparent specific mass, resistance to abrasion, resistance to uniaxial compression. The best-obtained results were the bodies of test fired at 1150 °C, among them, the mechanical resistance reached 34,38 MPa, abrasion wear of 10,9 mm and absorption of mid water of 9,83%. The manufactured adoquin showed acceptable technological properties for its use on streets, what would demonstrate the potentiality of the use of clay loam into pressed tiles.
