To prepare high-performance pervious concrete with excellent mechanical properties and permeability, an orthogonal test method is used to investigate the effects of water-to-binder (W/B) ratio, grading of small size aggregates, and target continuous void content on the mechanical properties and permeability of pervious concrete. The results show that the W/B ratio and grading of small-size aggregates have negligible effects on compressive strength and permeability. The target continuous void content is the key parameter in determining the permeability of concrete. The compressive strength must be controlled within a certain range to ensure a certain range of permeability. Only one permeability parameter is suitable for pervious concrete mix design.

摘要

To prepare high-performance pervious concrete with excellent mechanical properties and permeability, an orthogonal test method is used to investigate the effects of water-to-binder (W/B) ratio, grading of small size aggregates, and target continuous void content on the mechanical properties and permeability of pervious concrete. The results show that the W/B ratio and grading of small-size aggregates have negligible effects on compressive strength and permeability. The target continuous void content is the key parameter in determining the permeability of concrete. The compressive strength must be controlled within a certain range to ensure a certain range of permeability. Only one permeability parameter is suitable for pervious concrete mix design.
