Effect of High Temperatures on High-Strength Concretes Incorporating Copper Slag Aggregate

This study was performed to investigate the properties of high-strength concrete (HSC) incorporating copper slag as an iron-rich coarse aggregate under elevated temperatures. The compressive strength, splitting tensile strength, and ultrasonic pulse velocity values of copper slag aggregate HSC and limestone aggregate HSC with water-cementitious materials ratios (w/cm) of 0.40, 0.35, and 0.30 were compared at elevated temperatures up to 600 degrees. Results indicated that copper slag aggregate concretes showed better performance at room temperature and elevated temperatures in comparison with the limestone aggregate concretes. This was probably due to the strength characteristics and strong interface bond between copper slag aggregate and matrix. Thus, copper slag aggregate can improve the heat resistance of concrete.
