摘要
高性能水泥基复合材料的研究受到了广泛关注,纳米材料在促进水泥水化、提升水泥微观结构的致密性以及改善水泥基材料的力学性能和耐久性方面表现出色,赋予水泥基材料多样功能性的同时,减少水泥的添加量.从材料的机理层面出发,将不同维度的无机纳米材料对水泥基材料的水化、微观结构、力学性能以及耐久性等方面的影响进行了系统梳理,并展望了未来无机纳米材料改性水泥基材料的研究方向.
Abstract
The research on high-performance cementitious composites has received much attention.Nanomateri-als are excellent in promoting cement hydration,enhancing the densification of cement microstructure,as well as improving the mechanical properties and durability of cementitious materials,which can give the cementi-tious materials a variety of functionalities and reduce the amount of cement added.In this manuscript,the effects of different dimensions of inorganic nanomaterials on hydration,microstructure,mechanical properties and durability of cementitious materials are systematically sorted out from the mechanistic level of the materi-als,and the research direction of inorganic nanomaterials modification of cementitious materials in the future is proposed.
