▎ 摘  要

NOVELTY - High-efficiency graphene oxide concrete comprises 200-280 kg/m3cement, 150-230 kg/m3superfine admixture, 780-860 kg/m3tailing sand, 1010-1090 kg/m3graded gravel, 4.5-9 kg/m3superplasticizer, and 0.2-0.6 kg/m3slump retaining agent, 8-12 kg/m3impermeability component, 0.2-0.4 kg/m3graphene oxide solution, and 0.35-0.40 water-cement ratio control range. USE - High anti-seepage graphene oxide concrete. Uses include but are not limited to ports, reservoirs, dams, embankment and culvert gates, transportation, water storage, electricity generation, flood discharge and drainage. ADVANTAGE - The high anti-seepage graphene oxide concrete has improved strength and impermeability, and prolongs the service life of the hydraulic engineering concrete. The method is simple and easy to adjust. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparing the high-efficiency graphene oxide concrete.
