| 摘 要： | 通过取样进行氯离子扩散系数试验(RCM)和采用Autoclam在现场进行混凝土表面吸水性测试,对深港西部通道深圳侧接线工程的混凝土渗透性进行检测分析,表明该工程的混凝土具有较好的抗渗性;Autoclam测得的混凝土表面吸水性与RCM方法测得的氯离子扩散系数有较好的相关性,能够较好的反映混凝土的渗透性能。

| Abstract: | Based on the rapid chloride migration(RCM) test on sampling and in-situ concrete surface absorption test with Autoclam,the concrete permeability of Shenzhen side wiring project of Hongkong-Shenzhen western corridor was analyzed.Test result indicates that the concrete used in this project exhibits the adequate permeability resistance;and there is a good relation between surface absorption with Autoclam and chloride diffusion coefficient obtained from RCM.The permeability can then be determined both with the surface absorption and the chloride diffusion coefficient. |

| Keywords: | chloride diffusion coefficient surface absorption permeability |
