Ball milling was used to improve the dispersion of GO in a cement matrix in a planetary ball mill. Results indicated that the process had a negligible effect on the morphology of the GO but led to a 6.8% increase of the number of defects it contained. By adding 0.03 wt.% GO to the cement paste, its compressive strength increased by 9%, and the heat of hydration was increased 28%. The addition of GO accelerated the cement hydration, and decreased the porosity and pore size of the resulting cement paste, which were ascribed to the defects developed during ball milling and the functional groups on the GO that acted as nucleation sites for crystal growth during hydration. Ball milling provided an alternative method for the fabrication of GO-reinforced cement-based composites.

在行星式球磨机中，球磨用于改善GO在水泥基体中的分散性。结果表明，该工艺对GO的形貌影响可忽略不计，但导致其所含缺陷数量增加了6.8％。通过向水泥浆中添加0.03wt。％的GO，其抗压强度提高了9％，水化热提高了28％。GO的添加促进了水泥的水合作用，并降低了所得水泥浆的孔隙率和孔径，这归因于球磨过程中产生的缺陷以及GO上的官能团在水化过程中充当晶体生长的成核位点。球磨为GO增强水泥基复合材料的制造提供了另一种方法。
