Rebar
|
- Reinforcing Bar
- Deformed Bar
- Reinforcement in concrete
- Surface has scale and imperfections
- CRSI = Concrete Reinforcing Steel Institute
- CRSI states "rust on rebar is acceptable as long as the rust has not reduced the diameter"
- Cracking of #4 to #6 during field bending is common
- Bending of #4 to #6 should be done on a 2.5" pin
- All rebar is weldable
- However A706 has better weldability and is sometimes specified
- The English numbering system = eights of an inch
- Thus #4 = 4/8" or 1/2"
- The deformations adds to size diameter
