Model of Compressive Strength Degradation of Concrete under Both Freeze-Thaw Cycles and Compressive Loads

The frost resistance and compressive strength degradation of concrete under the simultaneous action of compressive load and freeze-thaw cycles are experimentally investigated in this paper. In order to track the strength degradation process, the nondestructive tests are carried out after each freeze-thaw cycle to get the residual strength for each specimen. Based on the experimental data, a variable, Kss, is proposed to describe the damage velocity and a prediction model of compressive strength degradation of concrete under freeze-thaw cycles and external load is established. By comparing with other researchers' indoor experiment data and outdoor inspection data, the model is proved to be reliable to predict the compressive strength degradation of concrete in a cold region.
