摘　　要：通过对聚丙烯系絮凝剂进行改性并优化水下不分散剂的配方,研制出工作性好、抗分散能力强、坍落度保持性能好、强度损失小的HLC-IV新型聚丙烯系混凝土水下不分散剂,并在连云港太平庄闸应急加固工程中得到了良好应用。After modifying the polyacrylamide flocculating agent and optimizing the ingredients of anti-washout admixture,a new HLC-IV anti-washout admixture was prepared whose performances such as workability, anti-washout resistance, retention of slump and compressive strength has been improved. The new anti-washout admixture was applied to strengthen Taipingzhuang floodgate with a satisfactory result.
