Reinforced Concrete - Advantages and Disadvantages

Concrete is one of the most versatile building material. Concrete is strong under compression yet weak under tension, brittle and limited ductility material. Therefore, a form of reinforcement is needed, steel bars reinforce concrete against tension only locally. Cracks in reinforced concrete members extend freely until encountering a rebar.

Advantage of Reinforced Concrete
High compressive strength
Adequate tensile strength
Fire and weather resistance
Durability
Economy to molde any shape
Low maintenance cost
Economy as a construction material
Less deflection
Use as precast structural components
Less skilled labor

Disadvantage of Reinforced Concrete
The tensile strength of reinforced concrete to compressive strength.
The main steps of using reinforced concrete are mixing, casting, and curing.
The cost of the forms used for casting RC is relatively higher.
For multi-storied building the RCC column section for is larger than steel section as the compressive strength is lower in the case of RCC.
Shrinkage causes crack development and strength loss.
