Anti-flocculating agent concrete admixture and preparation method thereof
The concrete admixture is prepared from the following components in parts by weight: 60 to 70 parts of a polyethyleneimine solution, 10 to 15 parts of polyethylene glycol, 0.1 to 1 part of a composite catalytic promoter, 4 to 10 parts of a catalytic stabilizer and 15 to 25 parts of water, wherein the composite catalytic promoter is obtained by compounding nano-zinc oxide, cellulase and amide hydrolase. The concrete admixture provided by the invention can effectively solve the adverse effects of high mixture viscosity, fast fluidity loss, difficult construction and the like caused by a flocculating agent on concrete, and the related preparation method is relatively simple, convenient to operate and suitable for popularization and application.
本发明公开了一种抗絮凝剂的混凝土外加剂，各组分及其所占重量份数包括：聚乙烯亚胺溶液60～70份，聚乙二醇10～15份，复合催化助剂0.1～1份，催化稳定剂4～10份，水15～25份；其中复合催化助剂由纳米氧化锌、纤维素酶、酰胺水解酶复合得到。本发明所述混凝土外加剂可有效解决絮凝剂对混凝土造成的拌合物粘度高、流动性损失快、难以施工等不利影响，且涉及的制备方法较简单、操作方便，适合推广应用。
