Abstract：In this paper,a new polycarboxylate high performance water reducing agent mother liquor was prepared by monomer such as dimethyldiallylammonium chloride,methyl allyl polyoxyethylene ether and acrylic acid. The best production process was obtained through experiments:Acrylic acid:TPEG2000=4.0:1.0(molar ratio),DADMAC dosage 20％(monomer total mole fraction), reaction temperature 70℃,reaction time 3.0～3.5 h. This product effectively solves the problem that the sand content is too high to cause the workability to fall,it has good adaptability to the concrete sandstone material,and has good retention of concrete slump and improvement to the concrete strength.
