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.
Is graphene safe?
"We do not yet know whether graphene flakes can become airborne and inhaled in a form that is dangerous during use."
Are carbon nanotubes the next asbestos?
"The difference with asbestos was that the hazards were not known or ignored; large-scale use meant large-scale production, resulting in emissions that weren't properly controlled, which in turn caused exposure at unsafe levels and then widespread disease. This should never have happened and should never again happen."
