针对在现场条件开展混凝土渗透性检测的要求,结合混凝土表层水吸附性ISAT法和混凝土保护层抗氯离子渗透性Permit试验的评价结果,对两种不同混凝土空气渗透性检测技术的CLAM test法和Schnlin法评估结果的可靠性和在现场条件下的可实施性进行了对比分析。研究结果表明空气渗透性检测CLAM test法和Schnlin法均是可靠的适于现场条件进行的检测方法,且两种方法的评价结果接近。与CLAM test法相比,Schnlin法的检测成本更低、检测速度更快、操作更简单,设备的安装与拆卸过程对混凝土结构表层完全无损害。 According to the requirements of concrete permeability testing in the field, combined with the evaluation results of concrete surface water adsorption ISAT method and concrete protective layer perchloride chloride resistance Permit test, two different concrete air permeability testing techniques CLAM test method and Schnlin method to assess the reliability of the results and the feasibility of the site conditions were compared. The results show that the air permeability test CLAM test and Schnlin method are reliable testing methods suitable for field conditions, and the evaluation results of the two methods are close. Compared with the CLAM test method, the Schönlin method has the advantages of lower detection cost, faster detection speed, simpler operation, and complete installation and disassembly of the equipment, completely without damaging the surface of the concrete structure.
