摘　　要：研究了以多种有机和无机材料复合,配制成的一种水下浇筑混凝土用抗分散剂。通过测定砂浆相关性能指标,确定了各组分复配的比例,并通过混凝土浇筑进行了验证性试验。研究结果表明,该复合外加剂可以满足水下浇筑混凝土施工要求,制备的水下抗分散混凝土主要技术指标符合规范要求。A new kind of admixture which is a compound of organic and inorganic components is developed for underwater non-dispersion concrete.The best proportion is determined by tests on the related properties of mortar.And the proportion is verified by concrete pouring tests.The results show that the admixture has favorable properties in underwater non-dispersion concrete.The main technical indexes of the underwater anti dispersive concrete are in conformity with the requirements of the specification.

关 键 词：抗分散剂 水下抗分散混凝土 絮凝剂
