Graphene oxide enhanced limestone coal series metakaolin cement and preparation method thereof
The invention relates to the technical field of cementing materials, in particular to graphene oxide reinforced limestone coal series metakaolin cement and a preparation method thereof. The concrete is prepared from the following raw materials: cement, modified coal-series metakaolin, limestone powder, graphene oxide, a polycarboxylate superplasticizer, standard sand and water, the modified coal series metakaolin is used as calcined clay in limestone calcined clay cement to prepare the novel limestone coal series metakaolin cement, the graphene oxide is used for enhancing the performance of the novel limestone coal series metakaolin cement, and the modified coal series metakaolin can improve the dispersity of the graphene oxide; graphene oxide can also provide nucleation sites for hydration products to promote hydration, so that the mechanical property and durability of the limestone coal series metakaolin cement are effectively improved, and the limestone coal series metakaolin cement has important significance in reducing the consumption of cement and solving the environmental problems of economy, carbon emission and the like.
本发明涉及胶凝材料技术领域，具体涉及一种氧化石墨烯增强石灰石煤系偏高岭土水泥及其制备方法；包括以下原材料制备而成：水泥、改性煤系偏高岭土、石灰石粉、氧化石墨烯、聚羧酸减水剂、标准砂和水；本发明使用改性煤系偏高岭土作为石灰石煅烧粘土水泥中的煅烧粘土制备新型石灰石煤系偏高岭土水泥，并使用氧化石墨烯来增强其性能，改性煤系偏高岭土可以提高氧化石墨烯的分散性，氧化石墨烯又可以为水化产物提供成核位点促进水化，有效提高了石灰石煤系偏高岭土水泥的力学性能和耐久性，对于减少水泥的用量、经济和碳排放等环境问题都有着重要的意义。
