[0002] Reinforced concrete, engineering is often referred to as reinforced concrete. It refers to the combination material that is jointly worked to improve the mechanical properties of concrete by adding steel mesh, steel plate or fiber in concrete. It is the most common form of reinforced concrete. Reinforced concrete can work together because of its material properties. First, steel and concrete have similar linear expansion coefficients, and will not produce excessive stress due to different environments. Secondly, there is good bonding force between steel and concrete. Sometimes the surface of steel is processed into ribbed (called modified steel) to improve the mechanical interlocking between concrete and steel. When this is still not enough to transfer the tensile force between steel and concrete, the end of steel is usually bent 90 degrees into a hook. In addition, the alkaline environment provided by calcium hydroxide in concrete forms a passivation protective film on the surface of steel, making steel less susceptible to corrosion in neutral and acidic environments.
