The invention provides a porous light pervious concrete terrace material and a preparation method thereof, and relates to the field of terrace materials. The composition of the material comprises thefollowing components in parts by weight: 160-200 parts of cement, 300-350 parts of river sand; 30-50 parts of black gold sand; 40-80 parts of high-titanium heavy slag; 50-100 parts of copper tailing powder; 20-40 parts of fly ash, 20-40 parts of silica fume; 20-40 parts of glass powder; 10-20 parts of basalt fiber; 10-20 parts of polypropylene fiber, 1-5 parts of sodium tripolyphosphate, 0.05-0.1part of monoethanolamine oleate, 0.1-1 part of sodium nitrite, 0.1-1 part of anhydrous sodium sulfate, 0.1-1 part of carboxymethyl cellulose, 5-10 parts of composite nano filler, 10-20 parts of polymer emulsion, 4-8 parts of early strength agent and 1-5 parts of water reducing agent. The pervious concrete terrace material is small in density (less than or equal to 2.76 m < 2 >/kg), good in water permeability (the water permeability coefficient is greater than or equal to 11.2 mm/s) and excellent in mechanical property (the 28d compressive strength is greater than or equal to 122.2 MPa, and the28d breaking strength is greater than or equal to 18.6 MPa).
