Abstract:
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.
