This study investigates the effect of adding a small concentration (0-0.5 wt. % addition by mass of cement) of graphite nanoplatelets (GNP) to cementitious materials. GNP-water-surfactant suspensions with various surfactant concentrations (0-20 mg/mL) and sonication times (0.5-6 h) are prepared and subjected to different protocols (long-term standing and centrifugation). Then, dispersion and stability are qualitatively observed through digital imaging and scanning electron microscopy after long-term standing and quantitatively evaluated by calc...
