The compressive strength and elastic modulus tests for two strength grade concrete specimens are carried out at different temperatures (20°C、100°C、300°C、500°C、700°C) and different heated times (1h、2h、3h), and the compressive strength and modulus of elasticity are obtained. The effects on properties of concrete for different high temperature and heated time are compared. The test result shows that the compressive strength and modulus of elasticity of concrete reduce along with the increase of heated temperature, and the higher the strength grade of concrete is, the more notable the reduced value is. Under the condition of same temperature, the longer the heated time is, the more obvious the two values reduce. The way of heating the specimens for different time has less influence on the compressive strength and modulus of elasticity than one of resisting different heated temperature.
