Graphene having superb electromechanical properties is a attractive material for advanced and smart cementitious composite systems. Although its newly was synthesized, there are several patents and research studies for its use in cementitious materials.
I think the GO Powder can be defined as its dry solid form with high purity. The terms cannot be compared. The materials can be marketable in special solution with dispersing agent or as dry forms.
In my opinion, the platelets should be used in liquid form to allow its sufficient homogeneous distribution in cementitious composites rather than its powder form. However, dispersing agent type and amount of the solution must be checked in terms of suitability for cementitious systems.
