Let’s see how these two types of reinforcement differ:
- Smooth reinforcement has a diameter from 6 to 40 mm
- Ribbed reinforcement has a diameter from 5 to 60 mm
- Smooth reinforcement has lower adhesion to concrete
- Ribbed reinforcement adheres better to concrete
Criteria for choosing reinforcement
When choosing reinforcement for concrete structures, it is important to consider several factors:
- Load level on the structure
- Operating conditions
- Economic possibilities of the project
Ribbed reinforcement makes concrete 10 times stronger compared to ordinary reinforcement.
Smooth reinforcement is ideal for lightweight structures. It is also well-suited for auxiliary elements. Ribbed reinforcement is better suited for critical building structures, foundations, and structures with high loads.
