Poly carboxylate superplasticizer(PCA) and viscosity modifier(VMA) were used to prepare pervious concrete with different fresh conditions. The correlation between fresh paste properties(fluidity and cohesion) and hardened paste performances of pervious concrete(compressive strength, hydrological permeability and porosity) was studied. A further rheological investigation was also conducted to reveal a better understanding of the fresh paste in pervious concrete. The results show that, as the fluidity increases, the paste flows downwardly, leading a descending porosity along vertical direction. It helps to achieve a better porosity distribution uniformity by improving the cohesion of pervious concrete. The fluidity and cohesion of paste could be increased simultaneously, which yields a higher plastic viscosity and a lower yield stress when PCA and VMA are used at the same time. The flow velocity of paste is thus decreased sharply with no significant impact on bonding performance between paste and aggregate. Pervious concrete with the specific rheological properties shows a practicable workability and uniform pore structure.
