ABSTRACT

The Portland cement was provided by Cement Australia, West Footscray, and conforms to the requirements of Type I-Normal Cement, asdefined by the ASTM C 150. The chemical composite of the cement is shown in Table 1. Graphite oxide (4 mg/mL, water dispersion) was obtained from Graphenea (Spain), and the elemental propertie of GO is shown in Table 2. The morphology and chemical properties of GO and the GO solution were diluted with tap water, as shown in Figure 1.
