A hybrid admixture combining recycled carbon nanofibers (from industrial waste) and a geopolymer binder (e.g., alkali-activated slag) to reduce cement use, enhance flexibility, and improve surface quality.
Benefits:
- Quality: Increases flexibility by 25% (better crack resistance) and improves surface smoothness (closer to asphalt-like rideability).
- Cost: Cuts cement use by 40%, saving $5-$10 per cubic meter (e.g., $2M savings on a 200,000 m³ project).
- Sustainability: Reduces CO2 emissions by 30-50%, appealing to green funding (e.g., World Bank climate grants).
