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.
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.
