How is rebar typically used in construction?

Rebar, or reinforcing bar, is primarily used in construction to provide structural reinforcement in concrete. Concrete is strong in compression but relatively weak in tension. When rebar is embedded within concrete, it enhances the tensile strength of the structure, allowing it to better withstand forces that could lead to cracking or failure. This makes rebar essential for a variety of applications, including foundations, beams, slabs, and retaining walls.

Using rebar helps ensure that concrete structures can support heavy loads and endure various stresses over time, thus contributing significantly to the overall safety and durability of the built environment. Other potential uses for rebar, such as decorative elements, insulating properties, or drywall installation, do not align with its fundamental purpose in construction.
