REINFORCEMENT HANDBOOK - Structural Engineers

2012-8-2  Reinforcement includes deformed bars, plain bars, wire, fabric and steel products, all of which increase the tensile and compressive stress carrying properties of concrete. Steel reinforcement is also the essential contributor towards crack control of concrete structures. Reinforcing Bar A bar is a finished product rolled to close tolerances.

CRSI: Mill Test Reports

The mill reports certify that the reinforcing bar conforms to the project specifications and reveals the chemical composition of the reinforcing bar and mechanical properties. Reinforcing bars typically come in two primary grades: Grade 60, which has a minimum yield strength of 60,000 psi, and Grade 75, which has a yield strength of 75,000 psi.

Reinforcement Tables

Reinforcement. Reinforcing bars are generally designated as B6,B8,B10,B12,B16,B20,B25,B32 and B40, although B40 is not generally used. This is generally due to procurement and that the bending radius of the bar and required lap/anchcorage length can make it impractical in designs. The bars are not smooth but have raised ribs on the surface ...

Reinforcement Bar - an overview ScienceDirect Topics

Status of reinforcement bars includes bar damage, bond to the surrounding matrix, and bar cleanliness. Site experience shows that even fine wires that connect individual reinforcement bars remain undamaged. Examples are shown in Fig. 5.23.It is also reported that tensioning ropes in pre-stressed reinforced concrete structures are not affected (Zehr, 1998).

Reinforcement – Contamination and rust - concrete.org.uk

All reinforcement should be protected from contamination by grease, oil, mud, mould oil, excessive rust (especially if it is flaky) and ice, plus any mill scale or concrete that is loose. Once the reinforcement has been fixed, do not leave it exposed to the weather for long otherwise rust might form.
