Graphene Makes Concrete Twice As Strong While Reducing Carbon Emissions (inhabitat.com)
Paige.Bennett writes: In a recent study, University of Exeter's Center for Graphene Science used nanoengineering technology to add graphene to concrete production. The resulting graphene concrete is two times stronger than traditional concrete and four times as water resistant, but with a much smaller carbon footprint compared to the conventional process of making concrete. According to the research, the addition of graphene cuts back on the amount of materials needed in concrete production by nearly 50 percent and reduces carbon emissions by 446 kg per ton.
Bold claim considering CVD is the only viable way produce graphene.
CVD is not the only way to make graphene.
Graphene is currently way too expensive for a bulk product like concrete, but if a big market is available more research will go into mass production techniques. More research should go into reinforcing concrete with other substances as well. I have seen concrete reinforced with peat moss, coconut fibers, and shredded bamboo. These increase tensile strength, and shock absorption, but reduce compressive strength.
increase of up to 146% in the compressive strength, up to 79.5% in the flexural one, and a decrease in the maximum displacement due to compressive loading by 78% ... 88% increase in heat capacity ... decrease in water permeability by nearly 400% ... reduction by 50% of the required concrete material while still fulfilling the specifications for the loading of buildings.
09F91102 no, 455FE104 nope, F190A1E8 uh-uh, 7A5F8A09 that's not it, C87294CE no. Ah! 452F6E403CDF10714E41DFAA257D313F.
How much does it cost? Because lots of things are stronger than concrete. Steel, for example is like 20 times stronger than concrete in compression and basically infinitely stronger in tension.
