Graphene-enhanced, low-carbon concrete successfully laid at Northumbrian Water site

From lab to site: delivering the CoMLaG system

The lower-carbon concrete, known as CoMLaG (Combining Micronised Limestone and Graphene), was developed and trialled at the GEIC and Cemex’s National Technical Centre. The mix uses a ternary cement blend, replacing a portion of the high-carbon clinker with GGBS and micronised limestone. To counter the strength losses typically associated with clinker reduction, a graphene-based addition formulated at GEIC was introduced to enhance strength development.

Following extensive lab trials, the project team scaled production through a batch plant in the North East of England using site-available aggregates and raw materials. The successful site application demonstrated the real-world viability of the mix and laid the foundation for future optimisation and deployment.
