Carbon-based nanomaterials (CNMs) have been extensively used to modify cement matrix thanks to their extraordinary specific surface area, high aspect ratio, and high strength and modulus. This review focuses on the current status of research on CNMs modified cement composites, especially the progress made in the past decade (from 2011 to 2021). At first, the primary properties of typical CNMs used for manufacturing cement composites, the treatments used to effectively disperse CNMs in water and cement matrix, and the corresponding characterization methods are reviewed. And then, the effects of introducing CNMs on the properties of cement composites (both fresh and hardened) are also discussed in this work. Finally, the knowledge gaps and remaining challenges for future work are discussed.

碳基纳米材料工程水泥复合材料：综述

碳基纳米材料 (CNM) 因其非凡的比表面积、高纵横比以及高强度和模量而被广泛用于改性水泥基体。本综述重点介绍了 CNMs 改性水泥复合材料的研究现状，特别是过去十年（2011 年至 2021 年）取得的进展。首先，综述了用于制造水泥复合材料的典型 CNMs 的主要性能、用于在水和水泥基体中有效分散 CNMs 的处理方法以及相应的表征方法。然后，本文还讨论了引入 CNM 对水泥复合材料（新鲜和硬化）性能的影响。最后，讨论了未来工作的知识差距和剩余挑战。
