Synthesis of Highly Dispersed Graphene Oxide-functionalized Carbon Nanotubes Complexes and its Effect on the Reinforcing the Properties of Cement Paste
- 발행 : 2020.11.12
초록
In this paper, we investigated the performance of synthetic graphene oxide-functionalized carbon nanotubes (GF) to promote cement hydration and increase the mechanical properties of cement paste. The enhancement effect of GF on the various properties of cement paste was evaluated via the mechanical strength, X-ray diffraction, and heat of hydration of cement paste. The results clearly showed that GF incorporation into cement paste promotes the early hydration of cement paste, generates more hydration products, which results in the mechanical improvement of cement paste. The compressive and splitting tensile strength were increased by 32.17% and 17.31%, respectively, compared to ordinary Portland cement at 28 days of hydration.
