摘要
研究了三种不同配方的复合外加剂——萘系Ⅰ、萘系+氨基磺酸盐Ⅱ和氨基磺酸盐Ⅲ对混凝土性能的影响,利用SEM分析了混凝土试件的微观结构。结果表明:掺加萘系+氨基磺酸盐Ⅱ复合外加剂的混凝土试件有较高的抗折、抗压强度,试件结构致密且气孔分布均匀,是符合道路工程要求的一种优化方案。
Studied the effects of three different formulas of compound additives naphthalene-based Ⅰ ,naphthalene-based and aminosulfonic acid-based Ⅱ and aminosulfonic acid-based Ⅲ on the properties of roadway concrete, and analyzed the microcosmic structure of the concrete samples by SEM. The results show that naphthalene-based plus aminosulfonic acid-based Ⅱ compound additive is an excellent plan to accord the roadway engineering requirements, which makes concrete sample higher flexural and compressive strength, more compact structure and the distribution of the samples＇ pore homogeneous.
