▎ 摘　　要

NOVELTY - A single-layer cement-based wave-absorbing material with composite nano wave-absorbing agent comprises cement, 5-20 %mass silica fume, 30-40 %mass water, 0.01-0.1 %mass reduced graphene oxide, 1-3 %mass nano-ferric oxide, 0.2-1.5 %mass nickel-plated multi-walled carbon nanotubes and 0.1-0.5 %mass water reducer with respect to the content of cement. USE - Single-layer cement-based wave-absorbing material with composite nano wave-absorbing agent. ADVANTAGE - The single-layer cement-based wave-absorbing material is environmentally-friendly, has no radioactivity, and simple preparation process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of single-layer cement-based wave-absorbing material with composite nano wave-absorbing agent.
