渗透结晶型防水材料的防水机理试验

从微观上研究了CN2000B防水涂料的防水机理，通过扫描电镜试验和能谱分析的方法，对比分析了CN2000B防水涂料净浆、砂浆及渗透层的形貌、化学成分及其含量，然后根据元素含量的变化来推断该防水涂料在砂浆中的渗透深度.通过X衍射试验测出了该防水涂料渗入到砂浆中生成的晶体成分.试验结果表明：渗透深度随龄期的增长而逐渐增加，28 d龄期的渗透深度可达29.14 mm.该研究结果成功应用于对焦柳线石吉段隧道渗漏整治，可为今后的隧道渗漏整治提供借鉴.

Experimental Research on Waterproofing Mechanism of Capillary Crystalline Waterproofing Material

This paper dealeds with the study on the micro-mechanism of CN2000B waterproofing coating.The microstructure of motor,waterproofing coating and permeability layer was obtained through scanning electron microscopy (SEM).Their main elements were determined and their relative weights(percentage) were calculated with X-ray energy dispersive analysis (EDAX).The test result was compared.The depth penetrated through mortar was deduced form the variations of elements content in different depth.The results of this study showed that the depth increased with curing time,and the value reached 29.14 mm at the age of 28 d.This study was applied to treatment of tunnel seepage on Shimen-Jishou section of Jiaozuo-Liuzhou railway.It can also be used for reference to treatment of the seepage on transportation railway tunnel.
