New concrete with the addition of graphene is 150% stronger than usual

Graphene is a fantastic material made up of a single layer of interconnected carbon atoms. It is rightfully one of the most unique man-made materials in the history of mankind. Recently, scientists from the University of Exeter (UK) found another application for it - as an additive to create a new type of concrete.

To do this, the research team developed a technique for suspending graphene flakes in water, after which the resulting mixture is added to traditional concrete ingredients - cement and filler. The process is reportedly not costly and is fully compatible with existing concrete production technologies.

In the course of the experiments, it was found that the compressive strength of graphene concrete increased by 146% compared to ordinary concrete, and the flexural strength by 79.5%, while the water resistance decreased by 400%. The new material is fully compliant with British and European building standards.

The obtained indicators will significantly increase the service life of objects built from graphene concrete, and reduce its consumption during construction by about 50%. This will improve the environmental component of the process, since cement production is one of the main sources of CO 2 emissions. According to scientists' calculations, they will decrease by 446 kg / t.
