Results of studies performed on one hundred, 1100 day old, plain concrete prisms are presented. These prisms had been placed under sustained load at 28 days. Creep recovery behavior, upon unloading, is examined. A number of prisms were unloaded and immediately reloaded to determine the effect of this load cycle on creep. Elastic modulus and ultimate compressive strength tests were conducted to determine the effect of age and sustained load on these parameters.
