Effect of graphene nano-sheets on concrete mechanical properties**

混凝土是建筑业中使用最多的材料，具有抗压强度高、抗拉和抗折强度低的特点。通过多项研究表明，在水泥基材料中掺入纳米材料可以提高水泥基材料的力学性能，特别是抗拉强度。一种潜在的用于混凝土的纳米材料是石墨烯纳米片。*Zenyatta Ventures Ltd.希望评估从其位于安大略省的大型矿藏中添加石墨烯材料对混凝土性能的影响。因此，本研究的目的是确定添加石墨烯、氧化石墨烯和还原氧化石墨烯对混凝土增强的效果。将被研究的变量包括在混凝土配合比中添加的石墨烯材料的百分比。混凝土的性能将根据其强度进行评估。*为了确保该项目成果的顺利转移，Zenyatta的技术人员将参与并能够在该项目的每个阶段提供他们的投入。*研究成果将为加拿大带来经济和环境效益。它将减少建筑业使用的混凝土数量，从而减少水泥制造过程中产生的二氧化碳排放。此外，鉴于加拿大拥有世界第三大石墨烯供应量，该项目可能会带动加拿大石墨采矿业的进一步增长，这将为加拿大经济做出贡献，并创造就业机会。**

Concrete, the most used material in the construction industry, is characterized by its high compressive strength and low tensile and flexural strength. Through several research studies, it was shown that adding nano-material into the cement-based matrix could improve its mechanical properties, especially its tensile strength. One potential nano-material to use in concrete is graphene nano-sheets.****Zenyatta Ventures Ltd. would like to assess the effect of adding graphene material from its large deposit in Ontario on concrete performance. Therefore, the objective of this study is to determine the effectiveness of adding graphene, graphene oxide and reduced graphene oxide for concrete enhancement. The variables that will be studied include the percentage of the added graphene material to the concrete mix. The concrete performance will be assessed based on its strength. ****To ensure a smooth transfer of the results of this project, Zenyatta technical staff will be involved and able to provide their input at every stage of this project. ****The research findings will generate economic and environmental benefits for Canada. It will reduce the amount of concrete used by the construction industry, thus reducing CO2 emissions generated during the manufacturing of cement. In addition, given that Canada holds the world's third largest supply of graphene, this project could lead to further growth of the graphite mining industry in Canada, which will contribute to the Canadian economy and lead to job creation.**
