The distribution of temperature stress was calculated by finite element analysis. The results showed when the surface temperature of concrete was higher than 110℃, the temperature stress was more than 4 MPa without regard to the creep. This might be lead to the damage of the surface of concrete. At the same time, a lot of microstructure analysiss such as XRD, SEM, IR, HSA etc. were done to analysis the difference of the component and microstructre of concrete before and after corrosion. The results indicated that the decomposion of CSH gel and calcium hydroxide and the creation of dilatability calcium oxide were the internal reason of the deterioration of concrete in the corrosion form of high heat.

该文通过有限元方法计算了由于温度而产生的结构应力分布，计算结果表明当混凝土表面温度超过110℃时，如不考虑徐变时表层混凝土受到的温度应力将超过4MPa，这使得表层混凝土很容易因温度应力而破坏；同时通过X射线衍射分析、扫描电子显微分析和混凝土孔结构分析等多种微观结构测试手段，分析了混凝土受热前后的宏观性能以及微观组成和结构的变化，指出混凝土原水化产物如水化硅酸钙凝胶和氢氧化钙的分解以及膨胀性产物氧化钙的产生是高热腐蚀形式下混凝土破坏的内在原因。
