NOVELTY - Wave-absorbing cement composition comprises a surface layer and a bottom layer, where the surface layer comprises foamed polystyrene and silicate cement, where the filling rate of foaming polystyrene is 40-70 vol.% and the particle diameter of foaming polystyrene is 2-6 millimeter, and the bottom layer comprises 5-15 wt.% graphene/barium titanate powder and silicate cement, where the volume ratio of graphene and barium titanate is 2:1-1:2. USE - Wave-absorbing cement composition. ADVANTAGE - The wave-absorbing cement composition has frequency band of 8-18 gegaHertz and absorbing ability is greater than or equal to (-)12 decibel, and enhances absorbing performance of the cement.
