Reinforced concrete is a composite material that provides superior compressive and tensile strength, according to the Concrete Reinforcing Steel Institute. Commonly used in the construction of bridges and highways, reinforced concrete is one of the most economical and durable construction materials available.
The steel bars used to make reinforced concrete are created by pouring molten metal into casters before shaping the steel into bars. Cross-hatchings are used to secure the steel bars and to ensure that weight is shared equally between the steel bars and hardened concrete. Concrete is then poured over the assembled steel bars, which allows the finished composite material to provide superior durability.
