摘　　要：利用三种具有代表性的防冻泵送剂,来研究不同种类防冻泵送剂对混凝土性能的影响。结果表明:聚羧酸型防冻泵送剂较萘系防冻泵送剂掺量少、减水率大、保坍性能好,且有利于混凝土早期强度的提高。The study use three representative anti-freezing pumping admixture to research the effect of different anti-freezing pumping admixture on concrete performance. The results showed that the polycarboxylic acid type anti-freezing pumping admixture had lower dosage,higher water reduction rate and better skid-keeping performance than the naphthalene anti-freezing pumping admixture,and had significant improvement in early strength of the concrete.

关 键 词：聚羧酸型防冻泵送剂 萘系防冻泵送剂
