Brief overview of Reinforcement Concrete

This is a great instructional video for construction professionals. The video briefly describes the reinforcement concrete process.

Reinforced concrete (RC) stands for a composite material where concrete's comparatively small tensile strength and ductility are defied by the addition of reinforcement that contains greater tensile strength or ductility. The reinforcement is generally, though not essentially, steel reinforcing bars (rebar) and is typically implanted inertly in the concrete prior to concrete is arranged.

Reinforcing schemes are usually planned to withstand tensile stresses in specific areas of the concrete that may lead to undesirable cracking and/or structural failure. Modern reinforced concrete includes diversified reinforcing materials which are developed with steel, polymers or alternate composite material in combination with rebar or not. Reinforced concrete is also stressed (in compression) perpetually, in order to make the behaviour of the final structure more improved under working loads. Generally, it is called as pre-tensioning and post-tensioning.

For a solid, ductile and long-lasting construction the reinforcement should contain the following properties:

1. High relative strength
2. High toleration of tensile strain

3. Strong bond to the concrete, regardless of pH, moisture, and similar factors
4. Thermal compatibility, not producing intolerable stresses in response to modifying temperatures.
5. Strength in the concrete environment, regardless of corrosion or sustained stress for example.
