| 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. |
