Abstract Graphene oxide (GO) nanosheets were prepared via oxidation treatment of graphite and then the dispersion liquid of which was prepared by ultrasound vibration in. The thickness and plane size of GO nanosheets are less than 11.95 nm and within 50~900 nm respectively. There are many chemical groups such as hydroxyl, carbonyl and epoxy groups on GO nanosheets. The prepared composite of graphene oxide/cement composited of ordinary cement and 0.03% GO nanosheets presents the regular micromorphology of ordinary cement, which consists of polyhedron-like cement hydration crystals by interweaving, penetrating and embedding each other. The compressive and flexural strength of the composite of GO/cement after curing for 28 days increase by 76.2% and 86.1% respectively, in comparison to that of the ordinary cement without GO addition, correspondingly the porosity and average pore diameter as well as cracks decrease obviously too.
