Concretene

Concretene is graphene-enriched concrete.[1][2][3]

Properties

Graphene acts as a mechanical support, increasing strength by around 30%, and offers an extra catalyst surface for the chemical reactions that produce concrete. It improves bonding at the microscopic scale. The increased strength allows much less material to be used, reducing carbon footprint (8% of 2021 carbon emissions) and energy costs, although material costs are some 5% higher, producing a net 20% cost reduction.[1]

The graphene is added where the concrete is mixed, without affecting installation at the construction site.[1]

History

In 2019, GrapheneCA announced the availability of concrete-suitable graphene.[2]

The first use of concretene came in 2021, when it was used in the construction of a gym in Amesbury, United Kingdom.[1]
