Graphene Integrations supplies a graphene concrete additive, made in the USA, for ready-mix and precast producers who want to test graphene in their own mix designs. NanoTechCrete is a water-compatible concentrate dosed at 5% by weight of cement. In independent third-party testing in 2023 it gave a 67.7% gain in compressive strength. Pricing is by quote, and results depend on the mix.
What the additive is
NanoTechCrete is a graphene concentrate supplied ready to add, so it can fit into existing batching and mixing. Graphene is pre-mixed in a liquid carrier, never sold as dry flake or powder. Because the product is water-based, it counts as part of the mix water: total liquid stays at 0.45 times the cement weight, and the mix water is reduced by the weight of NanoTechCrete added. The typical dose is 5% by weight of cement, which is 5% of the cement, not of the whole mix. Any change to a mix design should be confirmed by the project engineer.
Full mixing amounts for bagged mixes and a cubic yard, plus pack sizes (1 gallon, 5 gallon and 55 gallon, with bulk on request), are on the graphene concrete additive page and the mixing instructions. The product is patent pending and made in the USA. It contains no carbon black.
What the tests showed — and what they did not
Independent third-party testing in 2023 measured a 67.7% gain in compressive strength at a 5% dose by weight of cement. That figure is a tested result in the mix that was evaluated. It is not a guarantee for every cement, aggregate blend, water-cement ratio or curing regime. We work with producers who test graphene in their own mixes before any change to a production design. For the method and context, read how the graphene concrete additive works and what we tested and the concrete strength results press release.
GI graphene additives in other applications are typically used at 1% to 7% by weight; this concrete product is specified at 5% by weight of cement. A practical trial plan is in how to run a graphene additive trial.

Frequently asked questions
Is this graphene concrete additive available in the USA?
Yes. We make it in the USA and are based in Charlotte, North Carolina. We supply concrete producers across the US. Pricing is by quote.
Do I need new batching equipment?
The concentrate is supplied ready to add so it can fit into existing batching and mixing. Follow the mixing, storage and safety instructions on the spec sheet and SDS. Confirm any mix-design change with the project engineer.
Will I get the same 67.7% strength gain in my mix?
Not necessarily. That result came from independent third-party testing in 2023 at 5% by weight of cement in the mix that was tested. Results depend on the cement, aggregates, water-cement ratio and curing. We test with you before any production change.
How do I request a quote or samples?
Use the quote request form or the samples page, email sales@grapheneintegrations.com, or call 704-659-3682. Ask for the TDS and SDS at the same time.
