STC Super Toughness Concrete
Ultra-high toughness concrete (STC) is a high-strength, high-toughness cementitious composite material with a flexural strength of more than 22 MPa formed after mixing with water and setting and hardening of a dry mix made of cement, mineral admixture , fine aggregate, steel fibers, ultrafine powder, and admixtures, which has higher toughness compared to UHPC.

Product Features
1. The combined structure substantially improves the bridge deck stiffness, thus effectively improving the asphalt surface layer stress state.
2. The STC layer is cement-based material with good temperature stability, which improves the working conditions of asphalt deck and greatly reduces the risk of damage such as failure of bond layer, rutting, and pushover.
3. It reduces the stress of steel panel and stiffening ribs under wheel load, and greatly improves the anti-fatigue life of steel bridge deck.
4. The high compactness of STC ultra-high toughness concrete layer makes the steel bridge deck in a good working environment and effectively reduces the risk of corrosion.
5.Rapid Deployment: Walkable in 18h, heavy traffic ready in 72h – 50% faster than epoxy alternatives 15.
FAQ
Q:What makes STC different from UHPC or ECC?
A: STC combines high toughness and strain-hardening of ECC with structural-grade strength of UHPC.
Q:Can STC be used in earthquake retrofitting?
A:Yes, it is ideal for retrofitting columns, walls, joints, and beams in seismic zones.
Q:Is STC pumpable or shotcrete-compatible?
A:Yes, STC can be sprayed or pumped with standard equipment
