英文摘要：
The orthogonal test of four factors at three levels was designed when the acrylic, methyl acrylic acid sodium, ammonium persulfate and self-made macromer were chose as factors. Based on this, the influences of poly carboxylic acid water reducing agent on the initial fluidity of cement paste was discussed. Finally, the optimal synthesis with polycarboxylate superplasticizer was determined.
