Abstract: 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.
