Thanks to graphene, “experts” in Exeter, England are working on a new type of concrete that is bigger, stronger, faster, lighter, cheaper, AND more environmentally friendly than current concrete.

A new greener, stronger and more durable concrete that is made using the wonder-material graphene could revolutionise the construction industry.
Experts from the University of Exeter have developed a pioneering new technique that uses nanoengineering technology to incorporate graphene into traditional concrete production.
The new composite material, which is more than twice as strong and four times more water resistant than existing concretes, can be used directly by the construction industry on building sites. All of the concrete samples tested are according to British and European standards for construction.
Crucially, the new graphene-reinforced concentre material also drastically reduced the carbon footprint of conventional concrete production methods, making it more sustainable and environmentally friendly.
The research team insist the new technique could pave the way for other nanomaterials to be incorporated into concrete, and so further modernise the construction industry worldwide.
The research is published in the journal Advanced Functional Materials, on Monday, April 23 2018.
Professor Monica Craciun, co-author of the paper and from Exeter’s engineering department, said: “Our cities face a growing pressure from global challenges on pollution, sustainable urbanization and resilience to catastrophic natural events, amongst others.
“This new composite material is an absolute game-changer in terms of reinforcing traditional concrete to meets these needs. Not only is it stronger and more durable, but it is also more resistant to water, making it uniquely suitable for construction in areas which require maintenance work and are difficult to be accessed .
“Yet perhaps more importantly, by including graphene we can reduce the amount of materials required to make concrete by around 50 per cent — leading to a significant reduction of 446kg/tonne of the carbon emissions.
“This unprecedented range of functionalities and properties uncovered are an important step in encouraging a more sustainable, environmentally-friendly construction industry worldwide.”
