The　inferior　mechanical　performance　and　freeze-thaw　(FT)　resistance　of　recycled　concrete　are　mostly　due　to　the　significant　water　absorption　and　porosity　of　recycled　coarse　particles.　In　this　study,　different　dosages　of　zeolite　powder　were　used　in　recycled　concrete.　A　series　of　macroscopic　tests　were　used　to　evaluate　the　workability　and　FT　durability　of　zeolite　powder-modified　recycled　concrete　(ZPRC).　X-ray　diffraction　(XRD)　and　scanning　electron　microscopy　(SEM)　were　used　to　reveal　the　micro-mechanisms　of　FT　resistance　in　ZPRC.　The　results　show　that　the　increase　in　zeolite　powder　content　leads　to　a　decrease　in　the　slump　and　water　absorption　of　ZPRC.　Additionally,　ZPRC　with　10%　zeolite　powder　has　superior　mechanical　characteristics　and　tolerance　to　FT　conditions.　The　higher　strength　and　FT　resistance　of　the　ZPRC　can　be　attributed　to　the　particle-filling　effect,　water　storage　function,　and　pozzolanic　reaction　of　zeolite　powder,　which　results　in　a　denser　microstructure.　The　particle-filling　effect　of　zeolite　powder　promotes　the　reduction　of　surface　pores　in　recycled　coarse　aggregates　(RCAs).　The　water　storage　function　of　zeolite　powder　can　provide　water　for　the　secondary　hydration　of　cement　particles　while　reducing　the　free　water　content　in　ZPRC.　The　pozzolanic　reaction　of　zeolite　powder　can　also　promote　the　generation　of　hydrated　calcium　silicate　and　anorthite,　thereby　making　the　microstructure　of　ZPRC　more　compact.　These　results　provide　theoretical　guidance　for　the　engineering　application　of　recycled　concrete　in　cold　regions.
