Press release
The liquid concentrate is dosed at 5% of the cement weight, mixed into the water first, and now comes with published amounts for bagged mixes and a cubic yard.
CHARLOTTE, NC — October 23, 2026 — Graphene Integrations today launched NanoTechCrete, its graphene concrete additive, together with published step-by-step mixing instructions. NanoTechCrete is a water-compatible liquid concentrate for ready-mix and precast concrete, mortar, grout, pavers and repair materials.
One dose, one method
NanoTechCrete is dosed at 5% by weight of cement, which is 5% of the cement, not of the whole mix. Because it 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. Users stir the NanoTechCrete into all of the mix water until the color is even, then add that liquid to the dry mix and mix for 5 to 10 minutes. The new instructions include worked amounts for 50 lb and 80 lb Portland cement bags, premixed bags, and one cubic yard.
“Contractors told us they wanted it simple, so it's simple: 5% of the cement weight, stir it into the water, mix as usual. The 67.7% strength gain came from independent testing, and the instructions are written so a crew can get it right on the first batch.”
The data behind it
At that 5% dose, the graphene concentrate increased concrete compressive strength by 67.7% in independent third-party testing in 2023, and concrete with 5% graphene increased water resistance by 25%. Results depend on the cement, aggregates, water-cement ratio and curing, so the company recommends a small trial batch against the same mix without NanoTechCrete, and any mix design change should be confirmed by the project engineer.
Packs
NanoTechCrete is offered in 1 gallon jugs, 5 gallon pails and 55 gallon drums, with bulk on request. It is patent pending, made in the USA and contains no carbon black. Graphene is supplied pre-mixed in the liquid, never as a dry powder.

Concrete strength and embodied carbon
Cement is the binder in concrete. Its production releases CO₂ through limestone conversion and energy use, as explained by the IEA. That makes cement quantity an important part of a concrete carbon assessment.
GI’s additive achieved +67.7% compressive strength in third-party testing at the tested 5% supplied-additive dose by cement weight, not 5% pure graphene. This validated strength result supports investigating lower-cement mixes; it does not establish how much cement can be removed. Candidate mixes must meet the same required performance.
Conditional example: if 100 kg of Portland cement is actually avoided at the same required performance, gross avoided cement A1–A3 impact is 100 × 0.919 = 91.9 kg CO₂e. The 100 kg is an example assumption, not a reduction demonstrated by GI. The official US industry-average Portland cement EPD, revised July 2026, Table 4, gives 0.919 kg CO₂e/kg using 2019 production data, covering A1–A3, raw materials through manufacturing—not a current-year plant measurement or whole-life concrete footprint. CO₂e means carbon dioxide equivalent.
This is gross avoided cement-production impact, not measured GI net savings. Net savings require matched-performance mix validation and a consistent lifecycle comparison including additive manufacture, carrier, packaging, transport and all changed mix inputs. Unknown additive impacts are not zero. The strength result does not automatically establish cement reduction, longer service life or carbon capture.
