NOVELTY - Pumice concrete with electromagnetic wave absorption function, comprises 20-35 wt.% cement, 15-35 wt.% sand, 35-40 wt.% wave-absorbing material, and water (remaining amount). The wave-absorbing material is a composite material of pumice aggregate, poly (3,4-ethylenedioxythiophene), reduced graphene oxide and ferroferric oxide particles. The particle diameter of pumice bone material is 15 mm, porosity is more than 75%, inner aperture is 120 mu m, layer number of reduced graphene oxide is 8 and transverse size is 20 mu m. The mass ratio of poly (3,4-ethylenedioxythiophene), reduced graphene oxide and ferroferric oxide is 1:0.15:0.35:0.15. The method for preparing pumice concrete with electromagnetic wave absorption function utilizes alkaline reagent, solution of graphene oxide and reducing agent, ferrous and ferric ion, cement, sand, wave absorbing material and water, where the reducing agent is ascorbic acid, the alkaline reagent is aqueous ammonia water. USE - Used as pumice concrete with electromagnetic wave absorption function. ADVANTAGE - The concrete has excellent electromagnetic wave absorption function, and can be prepared by simple method.
