    Effect of Nanosilica on Impermeability of Cement-Fly Ash System by Huaqing Liu, Yan Zhang, Ruiming Tong, Zhaoqing Zhu, Yang Lv

    Published 2020-01-01
    “…Cement hydration was accelerated by adding NS, and probably, the pozzolanic reaction of FA was slightly hastened because NS not only consumed calcium hydroxide by the pozzolanic reaction to induce the cement hydration but also acted as nucleation seed to induce the formation of C-S-H gel. NS obviously refined the pore structure, increased the complexity of the pore structure, and improved the microstructure, thereby significantly improving the impermeability of the cement-FA system. …”
