Carbon Nanotubes (CNTs)

Miguel Angel Gomez Aristizabal at the National University of Colombia developed carbon nanotubes from coconut shells to reduce steel corrosion in cement by up to 70%.

Eden Innovations Ltd showcased its carbon nanotube technology and EdenCrete® product at the Aarhus Power-to-X Symposium 2026 in Denmark. This participation highlights the potential of carbon nanotubes in reducing the CO2 footprint of construction materials, aligning with global trends towards sustainable construction solutions.

Researchers at Kyiv Aviation Institute published a review of 2021–2026 experimental studies on multi-walled carbon nanotubes (MWCNTs) in reinforced concrete, finding that dosages of 0.05–0.15% by weight of binder increase crack initiation moment by 20–42% and reinforcement bond strength by 16–35%. The findings support broader use of carbon nanotubes as a concrete additive, with identified synergistic effects when combined with fiber reinforcement or micro-fillers offering a pathway to more ductile structural composites.

The Advanced Carbons Council published an overview of graphene and other advanced carbon materials being adopted in construction, citing applications in concrete (Concretene, First Graphene, Versarien), asphalt, and corrosion-resistant coatings (Petronas). These developments indicate growing commercial deployment of graphene additives in construction materials, with documented performance gains in compressive strength, road durability, and steel protection at low material loadings.
