 Advantage and disadvantage of RCC

Advantage

1) Strength:- Rcc has very good strength in tension as well as compression.

2) Durability:- Rcc structures are durable if designed and laid properly. They can last upto 100 years.

3) Mouldability:- Rcc section can be given in any shape easily by properly designing the framework. 

4) Ductility:- The steel reinforcement imparts ductility to the rcc structures.

5) economy:- Rcc is cheaper as compared to steel as prestressed concrete.

6) Transporation:- the raw materials which are required for rcc i.e. cement ,sand, aggregate, water, and steel are easily availableand can transported easily. Now a days Raidy mix concrete is used,

7) Fire resistance:- Rcc structures are more fire resistant than other commonly used construction materials like steel and wood.

8) Permeability :- Rcc is almost impermeable to moisture.

9) seismic resistance:- Properly designed Rcc structures are extremely resistant to earthquakes.

Disadvantages

1) rcc structures are heavier than structures of other materials like steel, wood, and glass etc..

2) Rcc needs lot of formwork, centering to be fixed, thus required lot of site space and skilled labour.

3) Concrete takes time to attain its full strength.thus rcc structures can't be used immadiately after construction unlike steel structures.
