State four point of differences between reinforced concrete and fibre reinforced concrete.

1 Answer

Answer :

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.
