摘要：
The influence of both organic and inorganic additives to calcium aluminate cement on the processes of hydration and structure formation of concrete both at normal and elevated temperatures is investigated here. The results of investigating phase transformations in hardened calcium aluminate samples during heating from 20 to 900 degrees C are given. The structure change mechanism and the reasons for the reduction of the strength of concrete under the influence of high temperatures are described.
