Reinforced concrete (RC) is a composite material in which concrete's relatively low tensile strength and ductility are counteracted by the inclusion of reinforcement. Durability in the concrete environment, irrespective of corrosion or sustained stress for example. Thermal compatibility, not causing unacceptable stresses in response to changing temperatures. Good bond to the concrete, irrespective of p. In the United States, the most common methods of doing this are known as pre- tensioning and post- tensioning.įor a strong, ductile and durable construction the reinforcement needs to have the following properties at least: High relative strength. Reinforced concrete may also be permanently stressed (in tension), so as to improve the behaviour of the final structure under working loads. Modern reinforced concrete can contain varied reinforcing materials made of steel, polymers or alternate composite material in conjunction with rebar or not. Reinforcing schemes are generally designed to resist tensilestresses in particular regions of the concrete that might cause unacceptable cracking and/or structural failure.
The reinforcement is usually, though not necessarily, steel reinforcing bars (rebar) and is usually embedded passively in the concrete before the concrete sets. Reinforced concrete (RC) is a composite material in which concrete's relatively low tensile strength and ductility are counteracted by the inclusion of reinforcement having higher tensile strength or ductility.
