State four point of differences between reinforced concrete and fibre reinforced concrete.
Differences between reinforced concrete and fibre reinforced concrete:
Sr. No. |
Reinforced concrete (RCC)
|
Fibre reinforced concrete (FRC)
|
1 |
In this concrete, steel bars are used as reinforcement.
|
In this fibers are added as additional reinforcement in addition with steel bars.
|
2 |
Generally, load is taken by steel reinforcement.
|
Load is equally distributed in concrete though fibers.
|
3 |
RCC possess less fire resistance than fiber reinforced concrete.
|
FRC has more fire resistance than reinforced concrete.
|
4 |
RCC is susceptible to formation of surface cracks.
|
FRC resist formation of micro-cracks, as fibers act as crack arrester.
|
5 |
RCC gives ordinary finishing.
|
FRC gives extra smooth finishing.
|
6 |
RCC has more weight resulting difficulty in handling.
|
FRC is light in weight, hence easy to handle.
|
7 |
RCC has better workability.
|
FRC has poor workability due to improper mixing of fibers.
|
8 |
RCC has less shear and torsional strength.
|
FRC has more shear and torsional strength.
|
9 |
RCC is costlier than FRC.
|
FRC is cheaper than RCC.
|
10 |
RCC is used in all type of ordinary construction i.e. building, road, etc.
|
FRC is used in tunnel lining, runway, aircraft parking, repair of dams, etc.
