Abstract Using typical viscosity-reducing polycarboxylic acid superplasticizers at home and abroad, the four-part workability test method of "dosage - flow rate - expansion - gas content" was innovatively adopted, combined with compressive strength test, and three typical concrete viscosity grades of C25~C30, C50~C55 and C60~C70 in application were simulated with water-binder ratios of 0.45, 0.35 and 0.29, respectively. The application effects of different viscosity-reducing polycarboxylic acid superplasticizers were systematically tested.
