| 摘 要： | 采用压汞法研究近50年龄期的水工混凝土的微观结构。试验表明,混凝土碳化层较未碳化层孔径增大,总孔隙率变大,最可几孔径变大,使得混凝土碳化层强度低于未碳化层强度。 |
| 关 键 词： | 水工混凝土 碳化 压汞法 |

| Abstract: | Microstructure of approximate fifty years hydraulic concrete is studied by mercury intrusion pores method（MIP）. The results indicate that the pore diameter, total pore volume and most probable pore size of carbonated zone of the concrete enlarge better than uncarbonated zone,caused that carbonated zone strength is lower than uncarbonated zone strength. |
| Keywords: | hydraulic concrete carbonization mercury intrusion pores method（MIP） |
