    Abstract：This paper analyzes the influence law of different amount epoxy resin or styrene acrylic emulsion on mechanical properties，permeability and water-retention performance of recycled aggregate permeable bricks by comparison method. The microscopic composition and structure of cement/epoxy resin slurry is analyzed，which provided a reference for the optimization and application of recycled aggregate permeable bricks.
    Key words：recycled aggregate，permeable bricks，polymer，water-based epoxy resin
