The wonder material for new batteries & so many strengthening applications...

Composit Tech CEO Anton Ocunev shows yet another use for Graphene in construction. This time strengthening and lightweighting rebar.

🌍 Graphene in Composite Rebar: A Breakthrough in Construction Technologies
Modern construction demands materials that are not only strong and durable but also lightweight and resistant to corrosion and environmental stress. GFRP (Glass Fiber Reinforced Polymer) rebar has already proven itself as a viable alternative to steel. But with the integration of graphene, we are taking it to the next level.
🔬 What does the research say?
A study published in Composites Part B: Engineering (2021) showed that adding just 0.3-0.5% graphene nanoplatelets (GNP) into the composite matrix can increase:
Elastic modulus by up to 35%,
Tensile strength by up to 25%,
Resistance to microcracking and aging in aggressive environments (alkali, salt, UV exposure) by 30-40%.
💡 Why does this matter for rebar?
1️⃣ Higher strength and stiffness = smaller rebar diameters for the same load capacity. This reduces overall structural weight and transportation costs.
2️⃣ Corrosion and chemical resistance = perfect for marine and infrastructure projects (bridges, piers, tunnels).
3️⃣ Durability. According to tests (Construction and Building Materials, 2022), graphene-enhanced GFRP rebar retains up to 90% of its properties after 1000 freeze-thaw cycles and prolonged exposure to aggressive environments.
🌱 Economics & Sustainability
Graphene-enhanced composite rebar helps:
Extend the lifespan of structures up to 50 years or more without major repairs,
Reduce carbon footprint compared to steel due to lighter weight and corrosion resistance,
Cut down on rebar mesh volume by 20-25% thanks to improved material performance.
🔗 Conclusion
Graphene is not just a buzzword. It’s a real tool for advancing construction efficiency. We are already integrating graphene technology into our composite rebar production and are ready to deliver materials with outstanding properties to the market.
📢 What do you think — when will graphene composites become the new standard in infrastructure?
