| 摘 要： | 合成了一种含不同磷酸基个数的有机磷酸盐缓凝剂,并将其结构、缓凝性能及抗黏土性能进行了测试表征。混凝土试验测试结果表明,合成出的磷酸盐缓凝剂能延缓水泥水化,缓凝作用好,与聚羧酸减水剂(PCE)复配后,提高了聚羧酸减水剂(PCE)的保坍性能。同时磷酸基缓凝剂还具有很好的抗黏土性能,吸附性能测试表明,所合成的磷酸盐缓凝剂能减少蒙脱土对减水剂的吸附。

| Abstract: | A new structure of phosphate retarder with different amount of phosphate groups was systhesized.The chemical structures of these retarders were determined by Fourier transform infrared.The properties of setting time,anti-clay ability and adsorption properties of the phosphate retarders after compound with polycarboxylate acid-based superplastizer(PCE) were studied.The experimental results indicate that the phosphate retarders showe a good performance in terms of workablility retention,retarding ability and anti-clay ability,and the phosphate retarders can reduce the adsorption amount of PCE on montmorillonid. |
