Abstract:

This study employs a modified Hummers method to synthesize graphene oxide (GO), followed by its characterization using X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy, and Raman spectroscopy. Ultraviolet-visible (UV-vis) spectroscopy assesses the dispersion efficiency of GO in aqueous solution, revealing good dispersion of GO sheets. Subsequently, the rheological properties and flow diameter of GO-based cement composites are investigated with 0.03% GO incorporated into the cement matrix. Rheological measurements demonstrate that GO significantly influences the flow behavior, enhancing the viscosity of the cement system. Moreover, XRD and thermogravimetric analysis (TGA) data indicate increased hydration in the GO-incorporated cement composite.
