EVALUATION AND SUMMARY OF A STUDY OF THE LONG-TERM MULTIAXIAL CREEP BEHAVIOR OF CONCRETE

The creep behavior of concrete subjected to triaxial compressive stresses and elevated temperature was evaluated. Strains were measured in cylindrical specimens subjected to 58 test conditions: 0--3600 psi compressions; curing times of 90, 183, and 365 days; two curing histories (air-dried and as-cast); and two temperatures (75 and 150 exp 0 F). The 90-day-cwed specimens were loaded for 12 months, followed by 5-month recovery. The other specimens were uniaxially stressed to 600 or 2400 psi for 5.25 or 4.75 years at 75 exp 0 F, followed by 77-day recovery. Strain measurements were made during the curing, loaded, and unloaded-recovery periods. This report describes the experiment setup and summarizes the results and recommendations.
