Rebar - Wikipedia

Rebar (short for reinforcing bar), known when massed as reinforcing steel or 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. Concrete is strong under compression, but has weak tensile strength. Rebar significantly increases the tensile strength of the structure. Rebar's surface is often "deformed" with ribs, lugs or indentations to promote a better bond with the concrete an…

THE EVOLUTION OF THE REINFORCING BAR

The first steel-reinforced concrete construction systems were used in the mid-19th century. These early systems used square twisted bars. The first materials specifications for steel reinforcing bars were developed in 1910. New "lugged" bars were introduced in the 1910s-1930s period. These bars were precursors of the modern deformed bars. A diamond pattern bar which was first used in the 1920s ...
