Reinforcing bars are tied in place to resist the forces of construction traffic, flowing concrete, and vibration during concrete placement. For additional guidance on tying reinforcing bars, see CRSI’s book “Placing Reinforcing Bars”. bit.ly/3LfAlnS

In the U.S., the size and grade designations of these carbon (“mild”) steel bars used to reinforce concrete are set by ASTM International. Always verify the ASTM specification and grade to ensure the reinforcement meets the strength, weldability, durability, & code requirements.

Yes. The presence of “tight” rust on reinforcing bars does not inhibit bond or development length. As a matter of fact, this “tight” rust can enhance the bond of the reinforcing steel to the hardened concrete. Learn more with this free Tech Note download: bit.ly/3NavZ1E
