Construction industry could decrease carbon footprint using new ‘green concrete’. Using nano-engineering technology, experts are working to develop a more sustainable, strong and durable concrete than existing ones.

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. Unlike previous attempts to use nanotechnology in concrete, which have focused on modifying the existing components of cement, the new technique allows a layer of graphene to be suspended in water. The method produces a high yield of concrete without defects, which can be […]
