摘要
介绍我国水泥混凝土抗硫酸盐侵蚀试验方法标准的发展情况,分析当前混凝土抗硫酸盐侵蚀试验存在的问题,主要包括试件尺寸、养护制度、侵蚀溶液、加速试验方法及评价指标。针对当前国内混凝土抗硫酸盐侵蚀试验方法标准的基本情况和存在的主要问题,提出应重视对新拌混凝土的抗硫酸盐试验研究,补充全浸泡条件下混凝土抗硫酸盐侵蚀试验方法,建立混凝土抗硫酸盐侵蚀的耐久性模型,并将耐久性作为主要评价指标。
This article describes the development of standard for test methods of cement and concrete′s resistance to sulphate attack in china,analyses the problems existing in the current test for sulphate resistance of concrete,ranging from the specimen size,curing condition,corrosion solution,accelerated test methods to the assessment indices.In view of the basic situation and main problems concerning the standard for test methods of concrete′s resistance to sulphate attack in current china,it is suggested that we shall pay attention to the research on the sulphate resistance test of fresh concrete,supplement the test methods of concrete′s resistance to sulphate attack in the condition of full immersion,build the durability models of concrete′s resistance to sulphate attack and serve it as the main index for the evaluation.
