Abstract：In order to investigate the high temperature resistance of the new epoxy concrete,the compressive strength test at high temperature was carried out with temperature and temperature holding time as the parameters,and the failure condition of the test block were analyzed.The research shows that as the temperature rises,the damage degree of the new epoxy concrete gradually increases,and the compressive strength of the gradually decreases.At 100℃for 2 h,the compressive strength loss exceeds 85%,and at 200℃,the compressive strength is only about 3 MPa.The new epoxy resin concrete has poor high temperature resistance and is sensitive to high temperatures.Without external insulation measures,it is not suitable for high temperature environments and is diffi-cult to be used as the main material in structures that may be exposed to high temperature environments.Based on the test results,the formula for calculating the compressive strength of new epoxy concrete at high temperature is fitted.
