摘    要:为了揭示高性能混凝土在非力学破坏因素作用下宏观性能劣化与细观结构变化之间的关系,以冻融作用为试验条件,采用压汞法测试混凝土的孔结构,研究了高性能混凝土冻融耐久性与其孔结构变化的关系.研究证明,正是高性能混凝土良好的孔结构赋予其优异的抗冻耐久性.

关 键 词:高性能混凝土  冻融  耐久性  孔结构

Abstract:In this paper, in order to reveal the relationship between macro-properties deterioration and microstructure change under non-mechanical function, the relationship between durability and pore structure change of HPC is studied under the test of freezing-thawing .In the research, the method of mercury intrusion poremeasurement (MIP) is used to examine the pore structure of concrete. It is verified that the good pore structure gives the excellent durability to HPC.
Keywords:high performance concrete  freezing-thawing  durability  pore structure
