    Reinforced Concrete vs Prestressed Concrete | SkyCiv Cloud prestressing concrete steel bar

    Reinforced concrete and prestressed concrete are both reinforced with longitudinal and transverse steel bars, also known as rebar. The main function of the reinforcement is to strengthen concrete when it undergoes tensile stress.prestressing bar - definition - EnglishProduction of steel and metals, in particular cold drawn steel, threaded steel, concrete steel, quality steel, pipes, wire and mats, rolling of steel billets, for one's own account or for others, wire rod, rock and tunnel anchors, prestressing steel, bar steel, flat steelPrestressingPrestressing is the introduction of a compressive force to the concrete to counteract the stresses that will result from an applied load. There are two methods of introducing prestressing to a concrete, namely pre tensioning and post tensioning. Pre tensioning happens before the casting of the concrete. This is done by placing of high tensile steel tendons in a desired profile in which the concrete is to be cast.
