Garden Guides | How to Attach Rebar to Rebar

Reinforcing bar or rebar is used to add strength and rigidity to concrete and masonry in a whole host of construction-related applications. Because rebar has the same expansion coefficient as concrete, it is able to reinforce concrete without potentially damaging it from within by expanding too quickly.

4.2 This test method is applicable to members regardless of their size or the depth of concrete cover over the reinforcing steel. Concrete cover in excess of 3 in. (75 mm) can result in an averaging of adjacent reinforcement corrosion potentials that can result in a loss of the ability to discriminate variation in relative corrosion activity.
