Lightweight low-carbon pervious concrete and preparation method thereof

The invention discloses lightweight low-carbon pervious concrete and a preparation method thereof. The lightweight low-carbon pervious concrete is prepared from the following raw materials in parts by weight: 20-40 parts of mineral powder, 10 parts of red mud, 3-12 parts of water, 60-240 parts of coarse aggregate, 60-100 parts of high-molecular polymer waste, 10 parts of water glass and 10-14 parts of sodium hydroxide. Wherein the high-molecular polymer waste material is a high-molecular polymer waste material subjected to hydrophilic modification. According to the invention, the cable sheath waste is utilized and treated, and the excellent physical and mechanical properties and heat resistance of the cable sheath waste are utilized; meanwhile, the red mud is recycled, so that the accumulation amount of the red mud is relieved, and the ecological environment is protected; the use of cement is abandoned, so that the energy consumption and carbon emission are reduced, and huge economic and environment-friendly
