How to Place Reinforcement Bars in Concrete?

A reinforcement bar is a steel bar or mesh of steel wires used in reinforced concrete and masonry structures to strengthen and aid the concrete under tension. Proper placement of reinforcement bars, as per the specified drawings is vital for the structures performance. Additionally, anchoring, welding, forming bonds and hooks, and binding of reinforcement bars […](Reapproved 2006) REINFORCEMENT FOR CONCRETE Reinforcing bars are manufactured in both International System (SIcommonly known as metricmeasured in milli-meters), and U.S. customary (i n.-lb) sizes. The bar number for metric bar sizes denotes the approximate diameter of the bar in millimeters. For example, a No. 13 bar is about 13 mm in diameter (actually 12.7 mm).
