Fibre reinforced concrete is a recent material well fitted for applications in industrial floors on soil foundation. The cost of fibers is compensated by a faster construction process and a reduction in the number of expansion joints. The Fibres Mainly used are Steel Fibres, Polypropylene (PP) Fibres & Cellulose Fibres. The fatigue, impact and flexural strength are significantly improved when steel fibers are added to the concrete mix. Industrial floors are the type of structures wherein the application of steel fiber reinforced concrete (SFRC) is advantageous. During the service life these structures are subjected to cyclic and impact loads, requiring an adequate fatigue flexural strength and energy absorption capacity.
Types:Mainly three types –- SFRC – Steel Fibre Reinforced Concrete
- Synthetic Fibres Reinforced Concrete
- Natural Fibres Reinforced Concrete
AdvantagesBuilding a slab with FRC will have the following advantages:
- Faster & cheaper construction (From 10-30% less usually)
- Slab less thick so less concrete
- No wire mesh installation and less people needed
- Faster concrete pouring, especially with laser screed equipment
- It is possible to do more than one surface in one day
- It is possible to reduce number of saw-cuts
- Lesser joint spacing
- Cleaner, sharper edges
- Less maintenance of the slab (less cracks, less saw-cuts, better fatigue and impact resistance, etc.
