This study was executed to investigate the restrained stress development at early ages in axially restrained concrete prisms. It was cleared from the test results that the high tensile restraint stress was developed at an early age in high-strength concrete and that the inherent high tensile strength might not be utilized for the structural performance of high strength concrete members. An analytic calculation considering creep under varying stress and the time-dependent properties of concreteat early ages, was successfully performed to interpret the test results.
