多因素作用下水泥混凝土抗渗性研究

Study on the Impermeability of Cement Concrete under Multi-factor Actions

本次研究是用试验的方法,通过比较单因素、双因素和多因素作用组合对水泥混凝土抗渗性的影响,来分析各单因素在工程实际的多因素对水泥混凝土的综合作用中的影响以及对水泥混凝土抗渗性造成的实际影响。按照GB/T50082-2009试验规范,用RCM法进行抗氯离子渗透试验,得到混凝土渗透深度,从而计算氯离子在混凝土中的非稳态氯离子迁移系数来确定不同因素作用后的混凝土抗氯离子渗透性能。

The study operated in experiment method is aimed at investigating the role of each singte factor in actual engineering multiple factors action on cement concrete and the effect of each single factor on the impermeability of cement concrete, through the comparison of the impermeability of cement concrete experiencing single factor action, double factors action or multiple factors action. The impermeability of cement concrete experiencing different factors was reflected by non-steady state chloride migration calculated from penetration depth measured in the concrete＇ s resistance to chlorides ingression test in RCM method with reference to the test standard GB/TS0082- 2009.
