近年來高鐵、跨海大橋等大型工程建設(shè)對水泥基材料的性能提出了更高的要求。納米科技與納米材料是從微觀角度提升水泥基材料性能的重要手段，近年來，以納米二氧化硅、納米碳酸鈣、碳納米管、石墨烯等為代表的納米材料在水泥基材料性能優(yōu)化方面的研究有了長足的進展。目前的研究進展表明，納米材料可以從多方面提升水泥基材料的性能，包括加速水化，提升早期強度；改善水化產(chǎn)物的組成與形貌，增加水泥基材料微結(jié)構(gòu)密實度，提升力學(xué)性能與耐久性。就性能優(yōu)化程度而言納米材料在本領(lǐng)域具有巨大的應(yīng)用潛力。同時，分散性問題是目前納米材料在水泥基材料中應(yīng)用面臨的主要問題，提供成熟可商業(yè)化的分散性解決方案是納米材料應(yīng)用中亟待解決的問題。此外，目前對于用于水泥混凝土的納米材料的結(jié)構(gòu)設(shè)計與改性方面的研究也有可以繼續(xù)深化的空間。

In recent years, blooming construction of megaprojects has posed higher performance demand for cementitious materials. Nanoscience and nanomaterials are advisable approach to improve the performance of cementitious materials from a microscopic perspective. Recently, researchers have made significant progresses in applying nanomaterials such as nano silica, nano calcium carbonate, carbon nanotube and graphene in cementitious systems. Recent research progress has shown that nanomaterials improve cement & concrete performance through three aspects: hydration acceleration, hydration product optimization and microstructure refinement. Considering the degree of performance optimization, the application potential of nanomaterials is applaudable. However, the dispersion problem of nanomaterials has to be further solved and commercialized dispersion technique should be proposed. Moreover, structural modification of nanomaterials for construction still need to be further explored.
