Abstract: The reinforcing agent is used for improving compressive strength, flextural strength and penetration of permeable concrete. The effects of water reducing composition, early strength compositiont and viscosity modifying compositon on the performance of permeable concrete were studied. The compressive strength, flexural strength, and the permeability coefficient and the water permeability of the permeable concrete were measured by changing types and content of the various components in the reinforcing agent. The experimental results show that the preformence of concrete with the reinforced agent by 0. 3% of polycarboxylic superplasticizer, 1. 0% of early strength increasing agent and 0. 1%viscosity is more better.
