摘要
以冻融作用为试验条件 ,采用光学显微镜测孔法和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 。
After using method of optical microscope poremeasurement (OMP)and method of mercury intrusion poremeasurement(MIP)to study the pore structure of concrete,the relationship between frost durability of a high performance concrete and its pore structure changes is researched based on the freezing thawing test.It shows that the very good pore structure gives the high performance concrete the excellent frost durability.
