摘要
负温条件下,当有液相水存在时,水化仍在进行:当受冻前强度达到1.5MPa后,静水压力理论在砼的冻融破坏过程中已经占主导地位。
It was proved that hydration of the cement would still process, as long as liquid phase remained at negative temperature. However,when the compressive strength of concrete achived 1.5 MPa before freeze, the hydraulic pressure would dominate the damage cause of concrete by freeze-thaw course.
