Sintering process occupies 60-70% of total production costs during the manufacturing of bricks. In this work, specimens were produced at various temperatures in electrical furnace and physical properties such as plasticity, shrinkage, loss of ignition, density and porosity, water absorption and mechanical properties such as freezing resistance, compressive strength, and other mechanical tests were investigated. Specimens were fired at 800°C did not meet standard mechanical properties. On the other hand, specimens were fired at 900°C shoved higher compressive strength and other specimens also met the standard mechanical requirements. As a result, mechanical properties were found to be greatly affected by the firing temperature of brick.
