Abstract:Effects of temperature upon strength, stiffness, and toughness of mortars and concretes are given. Two mortars and two concretes varying in cement content, and one lightweight concrete were used in the investigation. Mortar cubes, briquets, cylinders, beams, and concrete cylinders were tested after a 24-hr preconditioning treatment at test temperatures which varied between -70 and 450 F. Test results at subnormal temperature showed that mortar and concrete properties generally increased as the temperature decreased. Test results at elevated temperatures were not as consistent but in general the properties first decreased as the temperature increased, then increased, and finally decreased. At 450 F the strengths of the mortars and concretes were about equal to those at room temperature, but the moduli of elasticity were con-siderably lower.
