Is the "graphene" in your concrete actually just cheap graphite?
Is the "graphene" in your concrete actually just cheap graphite?
The speaker highlights a critical issue in the graphene industry: many materials marketed as graphene are actually just graphite, which fails to provide the necessary performance benefits in cementitious systems. Concretene addresses this by carefully selecting its base material, a specific graphene nanoplatelet (GNP) from a partner who uses a plasma process, ensuring consistency and quality. This avoids the pitfalls of using ineffective or mislabeled materials.
The key to unlocking graphene's potential in concrete is achieving a stable and uniform dispersion within the highly heterogeneous mix. Concretene has developed a proprietary process that creates a blended admixture of graphene oxide (GO) and graphene nanoplatelets (GNPs). This combination is specifically engineered to ensure the graphene is well-dispersed throughout the concrete, which is crucial for achieving reliable and repeatable strength enhancements at an industrial scale.
Beyond the formulation, Concretene has also innovated on the production of a key component, graphene oxide. They have patented a cheaper, cleaner, non-Hummers method for producing GO. This vertical integration and process innovation are critical for making the final admixture cost-effective enough for the construction industry, moving the technology from the lab to a pilot plant for full-scale accreditation.
In this short video, you can learn:
* The critical difference between graphene and graphite for concrete applications.
* How a blend of graphene oxide (GO) and graphene nanoplatelets (GNPs) solves the dispersion challenge.
* The importance of a patented, cost-effective GO production process for commercial viability.
š **Clip Abstract** Many so-called graphene products are actually graphite, which is ineffective in concrete. This clip explains how Concretene uses a specific graphene nanoplatelet and a proprietary graphene oxide blend to ensure proper dispersion and performance.

How does adding a few grams of graphene let you remove hundreds of kilograms of cement?
How does adding a few grams of graphene let you remove hundreds of kilograms of cement?
The primary mechanism for CO2 reduction is not a direct chemical reaction but an indirect engineering benefit. By adding a small amount of the graphene-based admixture, the compressive strength of the concrete is significantly increased. This is the key performance uplift that enables a corresponding reduction in the most carbon-intensive component of the mix: the cementitious binder (clinker).
For any performance-specified concrete, where a certain strength is required, engineers can leverage this strength enhancement. If the graphene admixture provides a 20% strength uplift, the mix designer can reformulate the concrete with 20% less cement while still meeting the original design strength specification. Since cement production is responsible for roughly a kilogram of CO2 per kilogram of cement, this reduction directly translates to a lower carbon footprint for the final product.
Concretene targets a reliable and repeatable performance uplift of 10-20% in concrete and 20-30% in mortars at 28 days. This focus on a guaranteed minimum performance, rather than outlier maximums, is crucial for gaining the trust of civil engineers and specifiers. The entire value proposition is built on delivering this strength increase in a cost-neutral way, where the savings from using less cement offset the cost of the admixture.
In this short video, you can learn:
* The direct link between increased compressive strength and reduced cement content.
* How performance-specified concrete standards enable carbon reduction through material efficiency.
* The target strength uplift percentages for concrete (10-20%) and mortar (20-30%).
š **Clip Abstract** This clip explains the core value proposition of graphene-enhanced concrete. By increasing the material's compressive strength, engineers can redesign the mix to use significantly less cement, directly reducing both the carbon footprint and cost.
