Abstract:
This investigation is a study of the structural properties of concrete made with sulphate-resisting cement (Type V) and Saskatchewan fly ash. Tests were performed on cylinders exposed to temperatures of 70° to 450°F (21.4° to 232°C) for periods of six months and over. The properties of strength, elasticity, creep and creep recovery were studied for both sealed and unsealed specimens. Test results revealed that temperature had a minor effect on strength and stress-strain relationship for both sealed and unsealed specimens; however, the modulus of elasticity showed a continual decrease with a rise in temperature. Creep of unsealed concrete increased with an increase in temperature up to 160°F (70°C) and decreased thereafter, while creep of sealed specimens decreased with a rise in temperature, except at 350°F (177°C) where it was one and a half times that at 70°F (21.4°
