The technical index of pervious concrete can be divided into mixed index and hardened concrete index。
(1) Mix: Slump (5mm~50mm);
Setting time (initial setting not less than 2h);
Coating degree of slurry (uniform wrapping, hand clenched, metallic luster)。
(2) Hardened concrete: Strength (C15~C30);
Water permeability (not less than 1mm/s);
Porosity (10%~20%) 。
(3) Anti-freeze-thaw cycle: Generally not lower than D100。
