Effect of High-Alumina Nanotechnogenic Petrochemical Wastes on the Heat Resistance of Clinker Brick

Resumo

The use of high-alumina nanotechnogenic raw material as grog was found to be expedient for increasing the heat-resistance of clinker brick. As the content of aluminum oxide Al₂O₃ in a ceramic body compositions increases, the heat-resistance increases and the CLTE decreases when the clinker brick is fired (1250°C). For Al₂O₃ content in the ceramic body from 41 to 43% the heat-resistance of the clinker brick reaches its maximum value and ranges from 11 to 13 cycles. Regression analysis was used to obtain a mathematical model to determine the heat-resistance of clinker brick at points that were not present in the experimental series.
