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.

Through the study of metallographic specimen and the inclusions through electrolyzation under SEM, it is indicated that the Ti-deoxidized products are globular compound inclusions with the size of 1~3μm in this experiment condition. With the technical of ion beam thinner the inner structure of these inclusions can be observed, whose core is Ti-O and outer is Mn-S. Based on EBSD the phase composition has been analyzed and it indicated that these globular compound inclusions are Ti2O3 and MnS with nucleating center Ti2O3, which can prompt to nucleate IGF.
