PROS AND CONS OF RCC IN CONSTRUCTION
Reinforced
concrete is a combination of traditional cement concrete with reinforcements
(steel bar). This combination is made to utilize the compressive strength
of concrete and tensile strength of steel
simultaneously.
In
reinforced concrete, the components work together to resist many types of
loading. Concrete resists compression and steel reinforcement resists tension
forces.
Reinforced
concrete, as an economic building material, is very popular nowadays. It is
widely used in many types building around the world. Along with many
advantages, reinforced concrete also poses some disadvantages also.
PROS
- Reinforced concrete has a high compressive
strength compared to other building materials.
- Due to the provided reinforcement,
reinforced concrete can also withstand a good amount of tensile stress.
- Fire and weather resistance of reinforced
concrete is fair.
- The reinforced concrete building system is
more durable than any other building system.
- Reinforced concrete, as a fluid material,
in the beginning, can be economically moulded into a nearly limitless
range of shapes.
- The maintenance cost of reinforced
concrete is very low.
- In structures like footings, dams, piers etc.
reinforced concrete is the most economical construction material.
- It acts like a rigid member with minimum
deflection.
- As reinforced concrete can be moulded to
any shape required, it is widely used in precast structural components. It
yields rigid members with minimum apparent deflection.
- Compared to the use of
steel in structure, reinforced concrete requires less
skilled labour for the erection of the structure.
CONS
- The tensile strength of reinforced concrete is
about one-tenth of its compressive strength.
- The main steps of using reinforced concrete
are mixing, casting, and curing. All of this affects the final strength.
- 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.
