Abstract:
SP25 Beginning with a literature review on the effect of sustained high temperatures, this excellent publication reports new research on the effect of exposures up to 1600 F on compressive strength of concrete; designing prestressed concrete reactor vessels with temperatures applied in the range of 35 to 775 F; information for application to design of mass concrete dams; laboratory and field studies on the effect of temperature differentials on slabs; temperature expansion in continuous span bridges; temperature effect on the curing process; concrete construction in hot climates; water-reducing admixtures effect on temperature rise in mass concrete; and using thermoelectric modules to apply temperature changes to mechanically loaded structural models.

This work was undertaken as part of a study to investigate the effects of sustained elevated temperatures on portland cement concrete as related to its use in a prestressed-concrete-pressure-vessel-reactor.

Test results are presented of the creep, strength, elasticity and creep recovery of mass concrete which was tested in the temperature range of 35-205 F and under stress-strength ratios of 10-70 percent. Creep was enhanced by temperature but strength, elasticity and creep recovery were independent of its effects. The relation of creep to stress-strength ratio in the range of 10-70 percent was linear. Discussion of a hypothesis of the creep mechanism is also presented.
