Splitting Tensile Strength of Concrete Under Temperature Differences
Abstract
The concrete shotcrete layer of the tunnel in the high-temperature field during construction exist in significant temperature difference environment caused by the one side of the shotcrete layer in contact with higher temperature rock, and the other side is in contact with the lower temperature air. Stress deterioration degree of concrete under the temperature difference condition comes out and it whether to produce local cracks in concrete is unknown clearly in engineering. According to the site concrete loading case conditions, the lab splitting tensile strength testing study of 4 types of concrete samples experiencing temperature differences is made. Through the results of the concrete test, a temperature difference influencing law of the concrete strength under temperature differences condition has been initially collected. And the results can provide a reference for similar projects.
