concrete rebar
Concrete rebar, short for reinforcing bar, is a vital component in construction, providing tensile strength to concrete structures. Primarily made of steel, rebar's main functions are to increase the overall strength of the concrete, control cracking due to tensile stresses, and enhance the ductility of the material. Technological features of rebar include its ribbed surface which improves the bond with the concrete, and its high tensile strength which allows it to resist stretching. Concrete rebar comes in various grades and sizes, catering to different structural needs. Its applications are widespread, from small residential buildings to large-scale infrastructure projects like bridges, tunnels, and dams. The versatility and reliability of concrete rebar make it indispensable in modern construction.
