Hyperbranched graphene oxide cement-based composite material and preparation method thereof
The invention discloses a hyperbranched graphene oxide cement-based composite material and a preparation method thereof, and belongs to the technical field of civil engineering. The cement-based composite material contains cement and hyperbranched graphene oxide, and the mass of the hyperbranched graphene oxide is 0.1-0.3% of the mass of the cement. The multi-performance improvement application of the cement-based composite material is realized. The hyperbranched graphene oxide is compounded with cement to obtain the modified cement composite material, the working mechanics and durability of the composite material are improved, and on the basis of improving the mechanical property of the cement-based composite material, the problems of agglomeration and poor dispersity of the unmodified graphene oxide in the cement-based composite material are solved; the influence of the unmodified graphene oxide on the working performance of the cement is overcome, the curing capacity of the cement on chloride ions is also enhanced, and the preparation of the high-performance cement-based composite material in a severe service environment is realized.
本发明一种超支化氧化石墨烯水泥基复合材料极其制备方法，属于土木工程技术领域。水泥基复合材料含有水泥和超支化氧化石墨烯，所述超支化氧化石墨烯的质量为所述水泥质量的0.1～0.3％。实现了对水泥基复合材料的多性能提升应用。将超支化氧化石墨烯与水泥复配，获得改性的水泥复合材料，该复合材料的工作力学和耐久性能均有所提升：在改善水泥基复合材料的力学性能的基础上，解决了未改性的氧化石墨烯在水泥基复合材料中团聚、分散性差的问题，并克服了未改性的氧化石墨烯对水泥工作性能的影响，还增强了水泥对氯离子的固化能力，实现了恶劣服役环境下高性能水泥基复合材料的制备。
