    Here is another one for those who think FGR should do there own material Tests. I think this should be done by the Universities or the ARC Grahphene Hub members. In some cases it is a perfect fit for students or doctorade or post doctorade Research. It will be much better to support / organize this  then  try it on their own.

    The results presented here indicate that nanoengineering concrete through reinforcement with graphene leads to concrete composites with ultrahigh strength and at the same time it widens the range of functionalities. These materials will be of particular interest for the construction industry to develop new competitive structural applications. Besides enhancing the mechanical performance, we demonstrate that the novel graphene–concrete composites satisfy multiple uses, with the added functionalities derived from the intrinsic properties of graphene. Thus, we show that graphene–concrete composites act as a barrier against water infiltration, which is an extremely desired property for long durability of concrete structures. In addition, we demonstrate enhanced thermal stability mainly through the increase in heat capacity of concrete by incorporation of graphene.
    More importantly, it is evident that graphene‐reinforced concrete will have positive impact on the environment. First, when compared to other reinforcement methods such as carbon nanotubes and graphene oxide, our method of production and final product are nonhazardous. This, along with the decreasing price of graphene, due to its continuous production scaling up would allow the direct fabrication and incorporation of graphene‐reinforced concrete in the construction industry. Another way in which graphene‐reinforced concrete will have a positive impact on the environment is by contributing to the decrease of carbon emissions due to cement manufacturing. Specifically, the production of concrete accounts for up to 7% of the global CO2 emissions.28 We estimate that reducing the quantity of cement by 50% of the required concrete material, while still fulfilling the specifications for the loading of buildings, would lead to a significant reduction of 446 kg per tonne of the carbon emissions by the cement manufacturing (see Section S10 in the Supporting Information). These considerations make our graphene‐reinforced concrete a promising material for a better, more environmentally friendly construction industry.

    The observed resistivity of graphene‐reinforced concrete is also crucial for preventing corrosion when steel rebars are used as conventional reinforcement. This potential corrosion of steel, which is an electrochemical process forming corrosion cells, causes deterioration of steel‐reinforced concrete beams or columns through expansion, cracking, and eventual spalling of the steel rebars' cover.25 This decreases the bond strength between steel and concrete, thus leading to several damage to the overall structure. This incidence of damage is especially large in the structures exposed to deicing chemicals.25 However, due to its resistive heater behavior, graphene‐reinforced concrete can exclude the addition of such chemicals and yet keep the corrosion formation to minimum in cases when steel embedding is required. ….


    Who is doing the anti fouling paint work ? Personally I think this one and Fire Stop would be a perfect starting point for FGR.

    Have a nice day
