武汉长江隧道工程所处环境是封闭潮湿、高压富水的地下空间,因而对其材料的耐久性能要求极高。聚合物胶乳对水泥混凝土有良好的改性作用,本文研究了丁苯胶乳、羧基丁苯胶乳、聚丙烯酸酯胶乳和乙烯-醋酸乙烯共聚物乳液改性混凝土的工作性能、力学性能、抗冻性能和抗渗性能,并就其机理进行了分析。
Wuhan Yangtze River Tunnel project where the environment is closed humid, high pressure water-rich underground space, and thus the durability of their materials demanding. Polymer latex has good modification effect on cement concrete. In this paper, the performance, mechanical properties, frost resistance of styrene-butadiene latex, carboxylated styrene-butadiene latex, polyacrylate latex and ethylene-vinyl acetate copolymer emulsion modified concrete And impermeability, and its mechanism was analyzed.
