Reducing Embedded Carbon in Concrete Applications

Tuesday, 3 June 2025

Low carbon concrete is increasingly in demand and in some municipalities, is a required material. The challenge has been to reduce the amount of cement in the concrete design mix without sacrificing strength, workability and setup times.

Graphene has been successfully used in the form of a liquid or powder admixture at extremely low load factors (less than 0.10% by weight) to reduce the amount of cement needed by more than 20%, thereby significantly reducing the embedded carbon.

In addition, the concrete retains its base properties and in many cases, achieves strength more rapidly while reducing water permeation over the long term, increasing the life of the concrete products.
