摘要
以聚丙烯酰胺、膨润土和减水剂等有机无机材料复合,配制成水下不分散混凝土用絮凝剂。通过砂浆性能试验,优选絮凝剂各组分配比。通过混凝土水下浇筑试验,该复合絮凝剂满足水下不分散混凝土施工要求,主要技术指标符合规范要求。
A kind of flocculant for underwater non-dispersible concrete was prepared by mixing organic and inorganic components.The proportion of each component was determined by measuring the relevant performance index of mortar.And the verification test was carried out by concrete pouring.The results showed that the admixture meet the requirements of underwater non-dispersible concrete construction,and the main technical indexes meet the requirements of specifications.
