摘要
在水泥砂浆中掺加一定掺量的苯丙乳液、聚醋酸乙烯乳液、甲基纤维素、乳胶和硅粉,可以提高聚合物阻尼增强水泥砂浆的损耗因子和储存模量,为了研究这些掺料对混凝土长期性能的影响,采用能分别体现高阻尼混凝土抗冻融能力、抗氯离子渗透能力和抗渗能力的4个指标(即剥落量、耐冻融系数、通过电量和渗水深度)作为影响因素,在试验的基础上,应用模糊综合评定的方法评定了高阻尼混凝土的耐久性,为今后混凝土耐久性的综合评估提供了一种新的探索.
The loss tangent and storage modulus of cement mortars may be improved by adding some admixtures （ including styrene-acrylic, polyvinyl acetate, methycellulose, Latex and silica fume） , but the influence of these admixtures on long-term properties of concrete is worthwhile to be studied. Four effect factors （ mass loss, frostresistant coefficient, passed electric quantity and infiltrating water depth）, which reflect frost-resistant ability, chloride ion penetration-resistant ability and water-resistant ability, are introduced, and the durable ability of high damping concrete is evaluated by the method of fuzzy comprehensive evaluation on the foundation of experiments. The results provide a new probe for evaluating comprehensively the durable property of concretes.
