聚合物改性混凝土已经发展成为改良混凝土耐久性的一种重要方法。为此,本文通过对C40普通混凝土、丙烯酸酯乳液、羧基丁苯乳液三种混凝土的力学性能、吸水性能和干缩性能的对比分析,及对综合经济效益分析,得出结论:丙乳的性价比明显高于羧基丁苯。由此可见,丙乳将会有更广阔的发展空间。 Polymer modified concrete has been developed as an important method to improve the durability of concrete. In this paper, through the comparative analysis of mechanical properties, water absorption properties and shrinkage properties of C40 ordinary concrete, acrylic ester emulsion and carboxylated styrene-butadiene styrene-butadiene latex, and the analysis of comprehensive economic benefits, this paper concluded that the cost-effectiveness Significantly higher than carboxybutyl benzene. This shows that Propionol will have a broader space for development.
