Graphene oxide (GO) is a recently invented 2D nanoplane fiber. GO is typically produced via the chemicaloxidation and exfoliation of graphite. Some authors have also reported that reinforcing the cement matrix withGO results in the formation of calcium silicate hydrate (C-S-H) gel in the micropores, thereby enhancing theresultant composite's mechanical properties. Markedly few studies have examined the durability ofGO-cement-based composites. This proposed research program aims to examine the workability, hydrationkinetics, mechanical properties and the transport properties of graphene-cement composites using puregraphene, graphene oxide and reduced graphene oxide.Critical examination of the effect of the three types of graphene powders on the properties and performanceof cement based composites will allow for a better understanding of the type of form graphene is most suitablefor application to construction materials. In addition, the evaluation of the material chemistry, evolution of theproperties is warranted to shed light on the corresponding hydration mechanism.

石墨烯氧化物（GO）是最近发明的2D纳米纤维纤维。 GO通常是通过石墨的化学氧化和去角质产生的。一些作者还报道说，用Go加强水泥矩阵会导致微孔中硅酸盐水合物（C-S-H）凝胶的形成，从而增强了培养基复合材料的机械性能。显然，很少有研究检查了基于污水的复合材料的耐用性。该提出的研究计划旨在检查使用纯含碳酸烯，氧化石墨烯和氧化石墨烯降低的石墨烯水泥复合材料的可加工性，水合作用力，机械性能和运输特性。对三种类型的石墨烯粉末对基于基于形式的石墨化合物的特性和性能的化合物对三种类型的化能和性能的材料的影响，可以更好地理解形式的材料。此外，对材料化学的评估，保证的进化是有必要阐明相应水合机制的。
