Trial tests graphene-enhanced concrete flooring in harsh conditions

Swedish graphene producer 2D Fab and partners have started a trial of concrete flooring reinforced with graphite to test the floor’s performance in harsh weather conditions.

Graphene is an ultra-thin material made of a single layer of carbon atoms. It is a very strong material with high mechanical strength whilst being very lightweight. It is also an efficient conductor of heat and electricity.

The graphite-enhanced concrete flooring will be exposed to heavy traffic and wear. Weather conditions at the trial location are described as freeze-thaw, with temperatures frequently fluctuating between freezing and below, then thawing. This weather causes moisture inside concrete to repeatedly expand and contract, leading to deterioration in standard concrete.

The Swedish concrete flooring test hopes to show that graphene-enhanced concrete maintains its strength and durability in the test site, which is one of the toughest global environments. A member of the trial team, Mattias Jonsson, Peab, said:

“You’d be hard-pressed to find a tougher test.”

The test will last for two years, which is plenty of time for a thorough evaluation of the concrete flooring.

Whilst weather conditions in the UK are not as extreme as Sweden, there is an issue when pouring concrete in freezing weather. Fresh concrete can freeze before it gains strength. Concrete pouring can be postponed in severe weather conditions, or a cold weather mixture that contains accelerators and a higher cement content may be used. The Swedish trial could demonstrate that graphene-reinforced concrete is an alternative solution.
