As the most widely used material on earth, concrete creates a massive carbon footprint that scientists work to eliminate in various ways.
The world's first graphene-reinforced concrete slab pouring work was recently completed using Concrete. Research projects have shown what the fantastic material graphene can do in this regard. Now we're seeing the first real-world deployment of the technology: Engineers are using graphene to enhance "concrete" to create the foundations of a new gym in the UK.
As the world's strongest artificial material, graphene may have many other potential uses, including in construction. Scientists have successfully incorporated it into the concrete manufacturing to make the finished product stronger and more waterproof. At the same time, one research project even demonstrated how to recycle this graphene from old tires.
The newly poured concrete is the work of scientists from the University of Manchester and national engineering and construction companies. To form the material, the team added small amounts of graphene to water and cement, which both acted as mechanical support and provided an additional catalyst surface for the chemical reactions that turned the mixture into a concrete paste. The result is improved bonding on a microscopic scale, and the material is around 30% stronger than standard concrete.
Dr Craig Dawson from the University of Manchester said: "We have produced a graphene-based additive mixture that does not interfere when used. "This means we can add the additive directly at the batching plant where the concrete is produced. , as part of the existing system, so there will be no changes to production or construction crews laying the floors."
Concrete production accounts for approximately 8% of global carbon emissions. Because graphene concrete is much stronger than traditional concrete, a building would require much less concrete to achieve the same structural strength, which could result in a smaller carbon footprint and cost and significant savings in building materials.
Nationwide Engineering analyzed the data and claimed that if the concrete was used in the global supply chain, it could reduce emissions by up to 2% globally. The material costs about 5% more to produce, but because less material is required, the company estimates it can provide customers with 10% to 20% savings.
