What does the term 'rebar' stand for?

The term 'rebar' stands for Reinforcing Bar. This type of steel bar is commonly used to strengthen and support concrete structures. Concrete has high compressive strength, but it is weak in tension and can crack under tensile forces. By embedding rebar within concrete, the tension capacity of the composite material is significantly enhanced, allowing for structures such as beams, slabs, and columns to withstand greater loads and resist cracking.

The term 'reinforcing bar' accurately describes the purpose and function of rebar in construction, as it directly relates to enhancing the structural integrity of concrete by providing additional tensile strength. Understanding this terminology is critical for ironworkers, as it highlights the role rebar plays in construction projects, particularly in terms of safety and stability.
