摘　　要：传统评价混凝土渗透性的方法有吸水性试验、渗透性试验及离子扩散试验,但对混凝土多孔砖砌体的现场渗透性能目前还没有评价方法。本文利用透水性测试仪(GWT)对不同位置、不同龄期抹面砂浆的混凝土多孔砖砌体进行现场试验,得出了混凝土多孔砖砌体的渗透系数。试验结果表明,利用该方法能够反映位置不同、砂浆抹面龄期不同混凝土多孔砖砌体的渗透性变化。这种方法与传统方法相比具有不受场地时间制约、操作方便、数据更真实等优点。最后探讨了这种现场试验方法作为评定墙体渗透性的可行性以及存在的问题。Traditional assessment methods are absorbent concrete permeability test, permeability test and ion diffusion test, but the permeability of concrete block walls have not yet an evaluation method. By using concrete surface penetration instrument (GWT) for different locations, this article tests different age Plastering mortar and concrete block wall, obtained concrete block wall permeability. Experimental results show that, using this method can reflect the different positions, and different age mortar plastering's permeability changes in concrete block. Compared to traditional methods,the method has a lot of advantage that it is not limited by the venue and time constraints, easy to operate, and the data is more realistic. At last, we discuss the feasibility of assessments of the wall permeability by field test and improvement of the issue.
