Industrial floors are normally subjected to various types of loading. There will be heavy rack posts, material handling equipment like forklifts, stacked loads, heavy tanks and other processing machines. These floors need to cater to stringent standards, especially in food and beverage industries, where hygiene and appearance are of great significance in addition to strength and toughness. The normal practice in industries is to provide a concrete grade slab with reinforcement in the upper one-third layer to cater to shrinkage and crack-control. These grade slabs have to be designed as per the elastic method, and hence thickness provided is same as that of an unreinforced slab. As reinforcement is located in a specific region, it does not serve the purpose of crack control throughout the slab. To use the plastic analysis approach and design thinner sections, we need to provide a reinforcing material that can provide the required ductility in the slab. For this purpose, reinforcement needs to be provided at the bottom of the slab, either in form of bars, fabric or steel fibres. The current paper deals only with the provision of fibres in achieving the ductility.

Fibre adds ductility to an otherwise brittle concrete. As the concrete cracks, the steel fibres transfer tension across the crack, bridging it and thus guaranteeing a post crack load carrying capacity.

Testing results have shown that reinforced concrete performed outstandingly in following respects:

• Sufficient rotation capacity.
• Substantial load redistribution
• Ductility and deformation capacity.

Considerations: One major goal in the design of structures is predicted, ductile failure.The first crack should not be the last crack.

 Benefits (with using SFRC):

• Increases toughness
• Shear Strength
• Resists crack propagation
• Post crack flexural strength
• Fatigue resistance
• Durability
• Energy Absorption
