Abstract

The invention provides multifunctional energy storage concrete, application thereof and an energy storage concrete member, and belongs to the technical field of concrete. The multifunctional energy storage concrete is prepared from the following components in parts by weight: 300 to 600 parts of ordinary Portland cement, 30 to 100 parts of mineral admixture, 300 to 700 parts of quartz sand, 5 to 60 parts of conductive material, 4 to 8 parts of admixture and 120 to 250 parts of water. The conductive material is added into the concrete, and a conductive network can be formed in the concrete material, so that the concrete has electric energy storage and conduction functions. The energy storage concrete provided by the invention can be used as a structural member for energy storage, and can also be combined with other energy technologies (such as solar energy and wireless charging) to realize integration of power generation, storage and utilization.
