The Room Temperature Synthesis and Performance Study of Cationic Polycarboxylate Superplasticizer

Abstract:

In this paper, cationic polycarboxylate superplasticizer has been synthesized by using room temperature process with HPEG, AA, DAC and 3-S as the main raw materials. We investigated the effect of the dosage of different raw materials on the dispersing property of polycarboxylate superplasticizer, and we knew that AA: DAC: HPEG: 3-S = 4.5: 0.05: 1: 0.12 was the best molar ratio, the synthesized cationic polycarboxylate superplasticizer had excellent dispersity and mud resistance, and it was superior to commercially available ordinary polycarboxylate superplasticizer.
