Graphene and its application: A review
TL;DR: Graphene-based reinforcing fillers, however, are unable to be directly included into cementitious composites for industrial manufacture due to dispersion problems and high prices, therefore, it seems that commercialising graphene for cementitious materials may be more feasible if it were combined with ordinary fibres to reinforce cement as discussed by the authors .

Study on the nanoscale mechanical properties of graphene oxide–enhanced shear resisting cement
TL;DR: In this article , the effect of Graphene oxide (GO) on the tensile/compressive strength of cement-based materials has been investigated, and it was shown that the addition of 0.02 and 0.04wt% GO in cement could improve the shear strength by about 12 and 40%, respectively, which is mainly due to the enhanced cohesion.

Graphene oxide dispersions in organic solvents.
TL;DR: In all of these solvents, full exfoliation of the graphite oxide material into individual, single-layer graphene oxide sheets was achieved by sonication, and graphene oxide dispersions exhibited long-term stability and were made of sheets between a few hundred nanometers and a few micrometers large.
