| Zusammenfassung: | •Fly ash- and nanomaterial-added pervious concrete (PC) mixtures were tested.•Strength, durability, permeability, water quality and production cost were tested.•Although stronger and more durable, the nanomaterial-added PCs were costly.•All the PCs were good at the removal of fecal coliform and phosphate.•A PC needs to be selected depending on the application purpose and other factors.
Three optimized fly ash (FA)- and nanomaterial-added pervious concrete mixtures (PCNI, PCGP, PCNS) and one control PCCT were compared for five criteria: compressive strength, physical durability, permeability, water quality performance and production cost. Both nanoSiO2-added PCNS and nanoFe-added PCNI had a higher compressive strength (∼17MPa), a greater resistance to abrasion ( |
