Rebar - Wikipedia

Rebar (short for reinforcing bar), collectively known as reinforcing steel and reinforcement steel, is a steel bar or mesh of steel wires used as a tension device in reinforced concrete and reinforced masonry structures to strengthen and aid the concrete under tension.History · Use in concrete and masonry · Physical characteristics · Sizes and grades · Placing rebar

Reinforced concrete - Wikipedia

Reinforced concrete (RC) (also called reinforced cement concrete or RCC) is a composite material in which concrete's relatively low tensile strength and ductility are counteracted by the inclusion of reinforcement having higher tensile strength or ductility.History·

How is spacing of rebar calculated in a reinforced section ...

As we all know, in reinforced concrete sections, concrete takes care of the compression while steel takes the tension. But the problem is, how to provide this steel ? -> Do I provide a couple of large bars ? -> Do I provide many closely spaced sma...

The problem with reinforced concrete

Reinforced concrete is everywhere. But unlike plain concrete, which can last for centuries, reinforced concrete can deteriorate in decades as the reinforcing bars succumb to rust.

CRSI: Reinforcing Steel

Rebar is used in concrete to provide additional strength, as concrete is weak in tension, while steel is strong in both tension and compression. Steel and concrete have similar coefficients of thermal expansion, so a concrete structural member reinforced with steel will experience minimal stress as the temperature changes.

concrete reinforcing bar (rebar)

Besides mild steel, rebar is also made in stainless steel (cost-effective, for example, for concrete bridges where salt is spread on winter ice) and other specialty alloys. Almost all bars are “deformed,” that is, a pattern is rolled onto them which helps the concrete get a grip on the bar.[PDF]
