Abstract：Conducted experimental research on the permeability,mechanical properties,and freeze-thaw resistance of permeable concrete with different steel slag powder contents.The results show that the addition of steel slag powder improves the permeability,mechanical properties,and freeze-thaw resistance of permeable concrete.The permeable concrete with an optimal steel slag powder content of 15%has a permeability coefficient of 2.07 mm/s,a compressive strength of 30.82 MPa,and a flexural strength of 4.16 MPa.After 100 freeze-thaw cycles,the mass loss rate of the specimen is 4.17%.The relative dynamic elastic modulus of this specimen is 22.03%higher than that of the unadmixed group,and the compressive and flexural strength loss rates are 14.71 and 20.56 percent points lower than those of the blank group,respectively.
