A new type of concrete is set to apparently revolutionise the construction industry!
According to experts, traditional concrete, blended with graphene, creates a ‘superconcrete’ that is twice as strong as your typical material. Not only that, but it is also reported to be four times as water resistant too. Plus, it can also be used directly on construction sites.
With all of these added bonuses, this material is also much more environmentally friendly in comparison to traditional concrete. In fact, due to the way it’s made, the carbon footprint is drastically reduced with the material being more sustainable.
To create this, University of Exeter experts used nano-engineering technology to mix graphene into your typical concrete. Creating a new technique, researchers were able to suspend atomically thin graphene in water. With no defects and a high yield as well, this method is compatible with manufacturing requirements whilst being low in cost too.
Professor Monica Craciun described, “Our cities face a growing pressure from global challenges on pollution, sustainable urbanisation 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.”
The lead author of the publication added: “This ground-breaking research is important as it can be applied to large-scale manufacturing and construction.”
“The industry has to be modernised by incorporating not only off-site manufacturing, but innovative new materials as well.”
“Finding greener ways to build is a crucial step forward in reducing carbon emissions around the world and so help protect our environment as much as possible.”
“It is the first step, but a crucial step in the right direction to make a more sustainable construction industry for the future.”
