Effect of graphene oxide nanosheets of microstructure and mechanical properties of cement composites

- Graphene oxide (GO) nanosheets were prepared by oxidization and ultrasonic dispersion.
- GO nanosheets can regulate forming flower-like cement hydration crystals and sharply increase its toughness.
- The flower-like crystals were attributed to the template effect of GO naosheets.
- The research provides a pathway to significantly improving the toughness of cement composites.
