Abstract

The compressive strength as well as other technical properties of structural clay masonry blocks are usually significantly affected by the firing temperature. The present work studied the temperature control response of structural clay masonry blocks when changing the firing condition from 700 to 800°C. Structural clay blocks fired at 700°C in an industrial furnace were compared with those fired in a laboratory electrical muffle furnace at 800°C. Both water absorption and compressive strength tests were carried out for the different brick samples. The block sample fired at 700°C failed to attend both the water absorption and the compressive strength requirements for structural elements. By contrast, after 800°C firing, the laboratory sample attended the water absorption specifications and showed higher compressive strength within the Brazilian standards.
