Concrete is a material made from cement that is widely used because it has a high compressive strength, is resistant to water, is easy to mold, and is cheap to make. But concrete’s biggest problem is that it’s easy to break because it does not resist cracking well, has low tensile strength, and cannot take a lot of stress. Researchers have been successful in enhancing the quality of cement composites by using fibers, admixtures, and other cementitious materials. When it comes to building objects, nanotechnology could open up a whole new world. Building materials have made nanosized materials that are used to make cementitious materials stronger and last longer. For example, they stop microcracks from starting and spreading. One of the most well-known graphene derivative nanomaterials is graphene oxide (GO), which has a lot of active oxygen-containing groups on its surface, outstanding mechanical properties, and thermal conductivity. Researchers have found that adding small amounts of GO in various dosages increases the flexural, tensile, and compressive strengths of cement paste and mortar. The majority of studies have looked at cement paste and mortar. There are few GO-concrete studies. One of the most characteristic graphene derivative nanomaterials, graphene oxide (GO), has a huge specific surface area, outstanding mechanical properties, thermal conductivity, and a lot of active oxygen-containing groups on its surface. Small amounts of GO at various dosages boost the flexural, tensile, and compressive strengths of cement paste and mortar, according to researchers. Most researches have examined cement paste and mortar. There are few GO-concrete studies. This article review paper will be useful for engineers and researchers investigating the impact of GO on mechanical qualities and advanced nanomaterials in cement-based materials like concrete. It will also be a point of reference for further research.

水泥基氧化石墨烯复合材料：机械和微观结构性能综述

混凝土是由水泥制成的材料，因其抗压强度高、防水、易于成型且制造成本低廉而被广泛使用。但混凝土最大的问题是它很容易断裂，因为它抗裂性差，抗拉强度低，不能承受很大的应力。研究人员通过使用纤维、混合物和其他胶结材料成功地提高了水泥复合材料的质量。在构建物体方面，纳米技术可以开辟一个全新的世界。建筑材料已经制造出纳米级材料，用于使水泥材料更坚固、更耐用。例如，它们可以阻止微裂纹的产生和扩散。最著名的石墨烯衍生物纳米材料之一是氧化石墨烯 (GO)，其表面具有大量活性含氧基团，具有突出的机械性能和导热性。研究人员发现，添加少量不同剂量的 GO 可以提高水泥浆和砂浆的弯曲、拉伸和压缩强度。大多数研究都着眼于水泥浆和砂浆。GO-具体的研究很少。最具特色的石墨烯衍生物纳米材料之一，氧化石墨烯（GO）具有巨大的比表面积、突出的机械性能、导热性，以及其表面大量的活性含氧基团。据研究人员称，不同剂量的少量 GO 可提高水泥浆和砂浆的弯曲、拉伸和压缩强度。大多数研究都考察了水泥浆和砂浆。GO-具体的研究很少。这篇评论文章将有助于工程师和研究人员研究 GO 对混凝土等水泥基材料的机械质量和先进纳米材料的影响。这也将成为进一步研究的参考点。
