The permeability, compressive strength, splitting tensile strength and frost resistance of high performance pervious concrete specimens with different pore size and distribution were studied under different curing mechanisms. The results show that the permeability coefficient of curing 7d test specimens are not very different from that of curing 28d test specimens; the permeability coefficient increases with the increase of porosity; the compressive strength and splitting tensile strength decrease with the increase of porosity; in the early stage of high performance concrete curing, adequate humidity is conducive to strength growth; the splitting tensile strength measured in the test is 1/12~1/15 of compressive strength; When 5% sodium chloride solution is used as a freeze-thaw medium, the permeability and compressive strength of the concrete after freeze-thaw changed more obviously.
