Reinforced Concrete | What is Reinforced Concrete?
Reinforced concrete is one of the most versatile and durable construction materials available today. It combines concrete's compressive strength with steel reinforcement's tensile strength to create a structure that can withstand a variety of forces, including weight, tension, and environmental stresses.. By embedding steel bars (also called rebar) or mesh into the …
