| Abstract |
Traditional cement⁃based materials cannot meet the requirements of complex civil engineering, as their functions are limited. Moreover, cement⁃based materials must evolve to meet the demands of intelligent buildings. Intelligent buildings not only need materials with high strength and excellent durability performance, but also require diversified features such as heat resistance, fire retardance, self⁃cleaning, electromagnetic interference shielding, and ion curing. Additionally, requirements of the national new materials and new energy development strategy make energy saving and emission reduction a key point in the development and application of new building materials. Intelligent building materials can promote the multi⁃functional development of modern architecture, realize the building intelligence, and further advance smart cities. Therefore, more and more research is devoted to the multifunctional development of nano⁃modified cementitious materials, which aims to provide an application basis for the green transformation of modern cementitious materials and the smart transformation of buildings. This review, proceeding from the functional modification of cement⁃based materials by typical nano⁃component materials(e.g., nano⁃SiO2, nano⁃TiO2, carbon nanotube(CNT), and graphene oxide(GO)), describes the different effects of properties, incorporation methods, and contents of nanomaterials on cement⁃based materials. Additionally, the influence of different modification methods and various other factors on a building’ s thermal insulation, self⁃cleaning, fire retardance, electromagnetic interference shielding, and ion curing functions are analyzed from the perspective of different nanomaterial additions. Based on “nanomodification⁃functionalization” dependence, this paper proposes the concept of coordinated development of multiple functionalized nano⁃modified cement⁃based materials and finally provides guidelines and prospects for customizability in sustainable development of intelligent buildings. © 2023 Cailiao Daobaoshe/ Materials Review.
