Our graphene concentrate is a concrete additive dosed at 5% by weight of cement. In independent third-party testing in 2023 it gave a 67.7% gain in compressive strength. It is supplied ready to add, so it fits into existing batching and mixing. For background on the material itself, see what is graphene.

What higher compressive strength can mean
Higher compressive strength gives designers more options. Any change to a mix design, or to the amount of concrete in a project, should be confirmed by the project engineer with testing on that mix. Results depend on the cement, aggregates, water-cement ratio and curing.
Water resistance
Beyond strength, concrete with 5% graphene increased water resistance by 25%. Water resistance matters for structures exposed to water and weather, such as bridges, roads and sea walls.
Sea walls and coastal concrete
We have focused our concrete work on applications where strength and water resistance both matter, including concrete sea walls. We work with concrete producers who want to test graphene in their own mixes; long-term field durability still has to be shown project by project.
Next: reinforcement
We are extending our concrete work to reinforcement. See graphene rebar (in development).
Spec sheet summary
- Form: graphene supplied pre-dispersed in a liquid carrier, never as dry flake or powder.
- Carrier options: water-compatible concentrate for adding with the mix.
- Typical uses: ready-mix and precast concrete, tested in your own mix design.
- Handling: liquid product, so there is no dry graphene powder to handle. Follow the mixing, storage and safety instructions on the spec sheet and SDS supplied with each product.
The full spec sheet and SDS are available on request. Request a quote, samples or a spec sheet / SDS.

Frequently asked questions
How much graphene concrete additive do I use?
Our graphene concentrate is dosed at 5% by weight of cement. In independent third-party testing in 2023 that dose gave a 67.7% gain in compressive strength.
Do I need new equipment?
It is supplied ready to add, so it fits into existing batching and mixing.
Will it give the same result in my mix?
Results depend on the cement, aggregates, water-cement ratio and curing. We test with you in your own mix, and any change to a mix design should be confirmed by the project engineer.
Is it made in the USA?
Yes. We make our graphene in Charlotte, North Carolina. See our graphene dispersions and graphene products.
Is graphene concrete additive available in the USA?
Yes. We make it in Charlotte, North Carolina, and supply concrete producers across the US. Pricing is by quote.
