Effect of Ball Milling Time on Strengths of Hybrid Fiber ...

2020-9-23  Jing et al. 14 used ball milling to improve the dispersion of graphene oxide (GO) in the cement matrix. They noticed a negligible effect of the process on the morphology of GO, but a slight increase in defects was observed. Hence, ball milling provides an alternative method for the fabrication of GO-reinforced cement-based composites.
