氧化石墨烯混凝土在水泥混凝土路面中的应用

Application of Graphene Oxide Concrete in Cement Concrete Pavement

为了研究提高水泥混凝土力学性能的问题,在混凝土中掺入具有优异力学性能且可溶于水的氧化石墨烯,采用压力机、扫描电镜分析等手段进行力学性能测试以及微观形貌表征的观察,试验发现氧化石墨烯的加入可改善水泥混凝土水化产物形态、减少混凝土孔隙率,提高水泥混凝土的力学性能,增强混凝土的韧性,提高其抗压强度。

In order to study the problem of improving the mechanical properties of cement concrete,the graphite is blended with graphene oxide which has excellent mechanical properties and is soluble in water.Mechanical properties tests and microscopic characterization were observed by means of press and scanning electron microscopy.It was found that the addition of graphene oxide can improve the morphology of cement concrete hydration products,reduce the porosity of concrete,improve the mechanical properties of cement concrete,enhance the toughness of concrete and improve its compressive strength.
