NOVELTY - Permeable concrete containing porous hybrid fiber modified recycled aggregate comprises 1000-1200 pts. wt. porous hybrid fiber modified recycled aggregate, 280-320 pts. wt. cement, 90-100 pts. wt. water, 300-320 pts. wt. silica fume, and 6.5-7 pts. wt. water reducing agent. The preparation of the porous hybrid fiber modified recycled aggregate comprises dissolving polyacrylonitrile and polymethylmethacrylate in N,N-dimethylformamide, heating and stirring until the solid dissolves to obtain a spinning solution, using an electrospinning process to obtain fibers, placing the fibers in a muffle furnace for pre-oxidation and high-temperature carbonization in sequence to obtain porous carbon fibers, mixing and ultrasonically treating the porous carbon fiber and graphene oxide dispersion, adding recycled aggregate, stirring, and drying. USE - Used as permeable concrete containing porous hybrid fiber modified recycled aggregate. ADVANTAGE - The method is simple to operate. The concrete has good water permeability, and good mechanical properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the permeable concrete.
