氧化石墨烯对固废混凝土工程性能影响研究

The Influence of Graphene Oxide on the Engineering Performance of Solid Waste Concrete

针对建筑材料资源短缺和建筑能耗大的问题,制备一种绿色环保的新型建筑材料迫在眉睫。将不同比例的氧化石墨烯掺入固废混凝土中,对固废混凝土抗压强度、抗折强度、渗透性和耐久性进行测试和分析。试验结果表明,氧化石墨烯对固废混凝土工程性能具有显著影响,适量添加氧化石墨烯可显著提高混凝土的力学性能,氧化石墨烯可以减少混凝土孔隙率,提高混凝土的致密性,降低混凝土的渗透性,提高混凝土的耐久性。在实际工程中,可以考虑添加适量的氧化石墨烯来改善固废混凝土的性能,实现资源有效利用和环境的可持续发展。

It is urgent to prepare a new type of green and environmentally friendly building material in response to the shortage of building material resources and high building energy consumption.The compressive strength,flexural strength,permeability,and durability of solid waste concrete were tested and analyzed by adding different proportions of graphene oxide to the concrete.The experimental results show that graphene oxide has a significant impact on the engineering performance of solid waste concrete,and the appropriate addition of graphene oxide can significantly improve the mechanical properties of concrete.Graphene oxide can reduce the porosity of concrete,improve its density,reduce its permeability,and improve its durability.In practical engineering,adding an appropriate amount of graphene oxide can be considered to improve the performance of solid waste concrete,and achieve effective utilization of resources and sustainable development of the environment.
