Abstract
Creep, drying, shrinkage, modulus of elasticity and Poisson`s ratio of concrete are influenced by a number of factors, such as mix type, member thickness, curing condition and loading cases. Particularly, creep and, shrinkage in concrete have yet to be studied due to its complicated time-dependent properties. Also they are not clearly differentiated quantitatively. In this paper, the concrete tests of creep, modulus of elasticity and Poisson`s ratio were carried out at various ages of loading -7, 28, 90, 180 and 365 days in order to investigate and quantify its long-term properties. The test procedures and analysis of the test results were also described herein. The results of this study will make it possible to calculate effective prestressing forces considering time-dependent prestressing loss and evaluate the structural integrity of the prestressing system using the representative values derived from this property test.
