Scientists Create New Concrete Using Graphene


Scientists created a new greener concrete using graphene, according to a study conducted on April 23, 2018.

This study was conducted by researchers at the University of Exeter. The new technique uses nanoengineering technology to incorporate graphene into traditional concrete production. The new composite material is twice as strong and four times more water resistant than existing concretes and can be used directly by the construction industry on building sites.

The carbon footprint of conventional concrete production methods was reduced by using the new graphene-reinforced concrete material. Also, it is a more sustainable and environmentally friendly method. According to the researchers, the new technique could pave the way for other nanomaterials to be incorporated into concrete, and so further modernize the construction industry worldwide.

Professor Monica Craciun, co-author of the paper said, “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.” Moreover, use of graphene will reduce the amount of materials required to make concrete by around 50 per cent and carbon emissions will be reduced.

This study focusses on suspending atomically thin graphene in water with high yield and no defects, low cost and compatible with modern, large scale manufacturing requirements. This study is the first step and a crucial one in the right direction, which will help in developing more sustainable construction industries for the future and further, will reduce the amount of carbon emissions around the world.
