Impact of overburnt distorted brick aggregate on the performance of concrete at ambient temperature and after exposure to elevated temperatures
Impact of overburnt distorted brick aggregate on the performance of concrete at ambient temperature and after exposure to elevated temperatures
his study examines the mechanical and durability properties of five concrete mixes made with different replacement percentages (0 %, 25 %, 50 %, 75 %, and 100 % by volume of regular brick aggregates-RBA) of RBA by overburnt distorted brick aggregate (ODBA) before and following exposure to elevated temperatures (250, 400, and 600 °C). The compressive, splitting tensile strength and the flexural load of the beams increased by 17 %, 23 %, and 18 %, respectively, at 28 days, when 75 % RBA was replaced with ODBA. The porosity decreased for the concrete containing up to 75 % ODBA. Conversely, the compressive strength decreased as the temperature increased, which agrees with the increased porosity with the increasing temperature.

Abstract
his study examines the mechanical and durability properties of five concrete mixes made with different replacement percentages (0 %, 25 %, 50 %, 75 %, and 100 % by volume of regular brick aggregates-RBA) of RBA by overburnt distorted brick aggregate (ODBA) before and following exposure to elevated temperatures (250, 400, and 600 °C). The compressive, splitting tensile strength and the flexural load of the beams increased by 17 %, 23 %, and 18 %, respectively, at 28 days, when 75 % RBA was replaced with ODBA. The porosity decreased for the concrete containing up to 75 % ODBA. Conversely, the compressive strength decreased as the temperature increased, which agrees with the increased porosity with the increasing temperature.
