Summary Graphene oxide (GO) offers great potential as nanoscale reinforcement for cementitious material. In this work, the rheological behaviours of the GO-cement composite were investigated for the first time. It was found that the workability of cement paste (w/c=0.5) is significantly decreased with the addition of 0.02wt% GO sheets. The rheology tests results show that the GO sheets greatly increase the yield stress and viscosity of the cement paste. It is also found that the yield stress and viscosity of the GO-cement composite increase with increasing size of GO sheets. The reduction of workability is undesirable for the application of the novel GO-cement composite. Therefore, further research works are needed to improve the workability of the composite.
