▎ 摘　　要

NOVELTY - A cement-based graphene oxide-doped wave absorbing material comprises cement, fumed silica, water, graphene oxide, nano ferroferric oxide, nano nickel and water-reducing agent. The weight ratio of fumed silica, water, graphene oxide, nano ferroferric oxide, nano nickel and water-reducing agent is 5-30:20-50:0.01-0.1:1-3:0.7-2.5:0.1-1. USE - Cement-based graphene oxide-doped wave absorbing material is used for building material. ADVANTAGE - The cement-based graphene oxide-doped wave absorbing material has wide frequency band, and excellent microwave absorbing performance, and is environmentally-friendly and non-radioactive, and can be prepared by simple and convenient process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of cement-based graphene oxide-doped wave absorbing material.
