再生骨料混凝土制品复合外加剂及其应用
摘要：
本发明提供了一种再生骨料混凝土制品复合外加剂及其应用，所述复合外加剂由以下重量比的组分制成：硫酸钠20～30％；三乙醇胺1～2％；木钙5～6％；松香酸钠0.15～0.2％；NaOH？0.01～0.02％；二水石膏30～40％；其余为水。本发明的复合外加剂可用于制备再生骨料混凝土制品。本发明的复合外加剂可减少混凝土用水量，提高混凝土制品早期强度，同时改善拌合混凝土的和易性。
摘要（英）：

The invention provides a compound admixture for a recycled aggregate concrete product and applications thereof. The compound admixture is prepared from the following components in percentage by weight: 20 to 30 percent of sodium sulfate; 1 to 2 percent of triethanolamine; 5 to 6 percent of calcium lignosulphonate; 0.15 to 0.2 percent of sodium abietate; 0.01 to 0.02 percent of NaOH; 30 to 40 percent of dihydrate gypsum; and the balance of water. The compound admixture of the invention can be used to prepare the recycled aggregate concrete product. The compound admixture of the invention can reduce water consumption of the concrete, improve the early strength of the concrete product, and also improve the workability of concrete mixing.
