“刚性防水和混凝土结构自防水”系列报道之二 聚合物乳液改性防水混凝土性能研究

Performance Research on Polymer Latex Modified Waterproofing Concrete

用三种不同性质的聚合物乳液来研究聚合物对混凝土性能的影响,测量了不同聚合物掺量下,聚合物改性混凝土的力学性能。结果表明:由于聚合物成膜及其与水泥水化产物的相互作用,混凝土力学性能都得到了显著改善;聚合物性质不同,对混凝土渗透性能影响不同。

The effect of polymer on concrete is studied by three different polymer latexes.The paper analyzes the distinction of the mechanical property of the modified concrete with the addition of different dosages of polymer.The results show that the concrete is improved in mechanical property due to polymer film and the interaction of polymer and cement hydration products.Moreover,different polymer has varying influences on the permeability of the concrete.
