摘　　要：纳米碳材料以其独特的结构及微观形貌,优异的力学、电学特性等,在信息、材料、能源、生物制药等领域引发了革命性创新。近年来,纳米碳材料以极低的掺量,表现出对水泥基复合材料微观结构、宏观力学性能的改善,同时赋予传统水泥基材料导电性、压阻性等功能特性。本文结合纳米碳材料自身形貌及表面化学特性等,综述了近年来纳米碳材料对水泥水化及微观结构的影响,纳米碳/水泥基复合材料的力学性能及压阻性等,并指出当前存在的问题及未来可能的研究方向。Owing to the unique structure, morphology, extraordinary mechanical and electrical properties, carbon nanomaterials have triggered revolutionary innovations in the fields of information, materials, energy, biopharmaceuticals, etc. In recent years, the modification of cementitious composites with extremely low content of carbon nanomaterials has raised widespread attention. The application of carbon nanomaterials not only improves the microstructure and mechanical properties of cement-based composites, but also endows traditional cement-based materials with multi-functional properties, such as electrical conductivity and piezoresistive properties. Based on the morphology and surface chemistry of carbon nanomaterials, the hydration, mechanical strength, and piezoresistivity of carbon nanomaterials modified cementitious composites are reviewed in this paper, the existing problems are summarized and possible research directions for the future are proposed as well.
