Graphene 'a game-changer' in making building with concrete greener

Form of carbon incorporated into concrete created stronger, more water-resistant composite material that could reduce emissions

The novel "supermaterial" graphene could hold the key to making one of the oldest building materials greener, new scientific research suggests.

Graphene has been incorporated into traditional concrete production by scientists at the University of Exeter, developing a composite material which is more than twice as strong and four times more water-resistant than existing concretes.
