Manchester’s innovation pioneer has earned the world’s first score for sustainable construction using graphene concrete.


Construction company Nationwide Engineering will complete the laying of the world’s first graphene concrete slab designed for sustainability in a commercial environment on Tuesday, May 25, making part of history. The new material is about 30% stronger than standard concrete.Significantly cut Use of material..

Owned and operated by military veterans, the new Southern Quarter Gym in Amesbury’s Solsty Spark, just a few miles east of Stonehenge’s ancient monument, is scheduled to open in the summer of 2021. The venue for this innovative milestone has been made possible by a consortium. A venture between National Engineering and the University of Manchester.

The innovation team pioneered this groundbreaking material to significantly reduce CO.2 Emissions during construction. The production of cement (the “glue” of concrete) is one of the leading sources of carbon dioxide emissions worldwide, producing about 8% of the world’s CO.2 Emissions.

The addition of a small amount of graphene, a 2D material made up of a single layer of carbon atoms, enhances Nationwide Engineering’s new product, Concrete, by approximately 30% compared to standard concrete. This means that significantly less material is needed to achieve comparable structural performance. Reduce carbon dioxide emissions and costs.

The additional strength also reduces the need for rebar, saves on-site materials and time, and further promotes the environmentally friendly qualification of this construction method.

Nationwide Engineering estimates that Concreten’s 5% additional cost will be offset by material savings to achieve an overall 10-20% savings over standard RC30 concrete.

“In collaboration with the University of Manchester’s Graphene Engineering Innovation Center partner and structural engineer HBPW Consulting, we are rapidly evolving our knowledge and experience, positioning ourselves for broader industry expansion through the construction framework and relying on graphene enhancement. Became a company. Concrete. “

Nationwide Engineering has three existing five-year construction frameworks with network rails and two seven-year Government Crown commercial building frameworks.Network Rail promises 11% reduction in CO2 Emissions from the next four years, graphene reinforced concrete, show great potential to help achieve this goal.

How does Concretene work?Liquid concrete hardens in it Solid form Use Chemical reaction Known as hydration and gelation, the water in the mixture reacts with the cement to form a paste that dries and hardens over time.

Graphene makes a difference by acting as a mechanical support and as a catalytic surface for early hydration reactions, improving binding on a microscopic scale and improving the strength, durability and corrosion resistance of the finished product. I will.

The important thing is that Concrete can be used like standard concrete. This means you can pass cost savings directly to your clients without the need for new equipment or training in the batch or laying process.

Dr. Craig Dawson, Application Manager at the Graphene Engineering Innovation Center, further explains: “We have produced a non-stop graphene-based additive mixture in use, which means that the additives can be administered directly in a batch processing plant. If concrete is produced as part of an existing system, production or flooring. There is no change in the construction staff to lay.

“We were able to do this by scrutinizing the materials we were using with our colleagues at the University of Mechanical, Aerospace and Civil Engineering. We coordinated this approach with our suppliers. We can’t see it because we can use graphene from a single supplier, “he added. “This makes the supply more secure, making Concreten a more viable proposal.”

At Amesbury, pour 234m first.2 Construction of concrete took place on May 6th, with an additional 495 m2 It will be laid on Tuesday, May 25th to complete the concrete floor slab.The· Graphene Used by the May 25 infusion is supplied by Versarien plc.

Nationwide Engineering effectively creates a “living lab” in the Southern Quarter to manage and monitor the site during installation and subsequent operations, and to measure and evaluate the performance of materials.
