摘要
根据碱—集料反应理论,论述了防冻剂在水泥—水体系中的存在形式和水化反应实质,分析了掺防冻剂混凝上中的碱含量与负温度的关系。指出大掺量防冻剂混凝土中碱腐蚀的潜在危险。
The formation of antifrcezing admixturc in cement-water system is discussed, and the relation between alkali amount and temperature of concrete with antifreezing admixturc is analysed bascd on theory of alkali-aggregate reaction. However, a potcntial corrosion of alkali would be a problem when large amount of antifreezing admixture is used in concrete.
