Rebar, also known as reinforcement steel and reinforcing steel, is a steel bar or mesh of steel wires used in reinforced concrete and masonry structures to strengthen and hold the concrete in tension. To improve the quality of the bond with the concrete, the surface of rebar is often patterned.
Rebar is necessary to compensate for the fact that whilst concrete is strong in compression, it is relatively weak in tension. By casting rebar into concrete, it is able to carry tensile loads and so increase overall strength.
Different uses of rebar include:
-Used to provide resistance to support design loads.
-Used for durability and aesthetic purposes by providing localised resistance to limit cracking and temperature-induced stresses.
Provide resistance to concentrated loads, spreading it through a wider area.
Assist other steel bars in accommodating their loads by holding them in the correct position.
External steel tie bars to constrain and reinforce masonry structures, sometimes as a means of building conservation.
Reinforced masonry: Some masonry blocks and bricks include voids to accommodate rebar to carry tensile loads. The rebar is secured in place using grout.
