Rebar, a shortened version of reinforcing bars, is widely used in concrete construction to add strength and stability to structures, including bridges, buildings, walls, and pavements It's made of steel and goes inside the concrete before it hardens. It can be bent and shaped to meet the needs of a project and is available in a variety of sizes and grades to meet various strength requirements.
When the concrete hardens, it has high compressive strength, which means it can withstand being pushed together.
It has a lower tensile strength, which indicates it can crack and break when stretched or pulled. Rebar compensates for this weakness by adding tensile strength to the concrete. When tension or bending forces are applied to concrete, the rebar resists the force and assists the concrete in maintaining structural integrity.
Rebar is frequently designed and installed in a specific pattern to reinforce critical areas of the structure, such as corners, beams, and columns, where load-bearing capacity is greatest. Factors such as structural design, expected loads, and environmental conditions all influence the type and placement of rebar.
