RESEARCH ON EVALUATION OF PERMEABILITY OF CONCRETE BY DICHLOROMETHANE
-
摘要: 研究并确立了用二氯甲烷测量混凝土渗透性的参数浸泡时间t及评价参数GV,并与ASTMC1207-97评价混凝土渗透性的方法进行评价参数相关性的比较。结果表明:这两种评价混凝土的渗透性方法的评价参数满足指数函数的形式。Abstract: In this paper, immersion time ( t ) and evaluation parameter ( $GPV ) which are parameters evaluatingpermeability of concrete by dichloromethanewere set up. At the same time, ASTM C1202- 97 was used for the comparison ofrelativity of evaluation parameters. The experimental results show that these two kinds of evaluation parameters meetexponential function.
