摘要
随着工程环境日趋复杂,水泥基材料的耐久性问题成为其发展的制约因素。碳纳米材料可促进水泥水化、从微观角度优化水泥基材料内部结构,进而有效强化其耐久性。综述了碳纳米材料对水泥基材料耐久性强化的最新进展,重点讨论碳纳米材料的分散性、强化机理,并对碳纳米材料应用于水泥基材料中存在的问题及发展方向进行了探讨。
With the increasing complexity of the engineering environment,the durability of cement-based materials has become the key factor hindering their development.Carbon-based nanomaterials can promote hydration reaction,optimize microstructure of cementitious composites,and enhance their durability effectively.This review offers a retrospection of research efforts with respect to the reinforcement of cement-based composites durability by carbon-based nanomaterials,discusses carbon-based nanomaterials dispersion and strengthening mechanism.Meanwhile,the current challenges and future directions of the application of carbon-based nanomaterials in the cementitious materials are proposed.It will provide some ideas for the future research.
