Paper Title:
The Effect of Sodium Sulfate on the Dispersion of Polycarboxylate Superplasticizer
  Abstract

The effect of sodium sulfate on the dispersion of polycarboxylate superplasticizer (PC) was studied in this paper. The study of fluidity of cement paste shown that the carboxyl groups did more to improve the fluidity of cement paste than the sulfonic groups, and a quick loss of fluidity was much more likely arisen by slufonic groups in PC comparing with the carboxyl groups. The methods of zeta potential and fluidity of cement paste were applied to investigate the dispersal ability of cement particles when different PC used in the present of different concentration of sodium sulfate. The result showed that the sulfonic group was more sensitive to sodium sulfate than carboxyl groups in PC.
