Toughcrete/Toughcrete+ for Flooring Paving
SFRC (Steel Fibre Reinforced Concrete) has a distinct advantage over plain or reinforced concrete in “slab-on-grade”, i.e. industrial floorings, concrete pavements, ground slabs, etc. where the loads are both static and dynamic. Under dynamic loading, plain concrete slabs crack quite easily losing their capacity to carry loads. These cracks further enlarge with passage of time and need costly repairs. SFRC slabs on the other hand work on the principle of load redistribution.
Addition of Toughcrete or Toughcrete+ to concrete significantly improves the post-cracking strength of SFRC slabs. This is because of the crack controlling mechanism provided by Toughcrete/Toughcrete+, by transmitting some of the tensile stresses across the crack and also resisting growth of the cracks.
Reinforced concrete slabs, though fare better than plain concrete slabs, have disadvantage of the costly, laborious, time consuming and at times- hazardous process of installation of reinforcement mesh. Steel Fiber In Flooring provides excellent resistance to reduce breaks in hardened concrete. Hence, SFRC slabs are the best, most scientific and longer lasting solution for all types of floorings and pavements.
Benefits of Toughcrete & Toughcrete+ in flooring paving:
- Improved crack resistance
- High energy absorption
- High impact resistance
- High fatigue resistance
- Increased shear resistance
- Increased flexural strength
- Better corrosion resistance
- Full reinforcement of the slab
- Better overall performance of the slab
Commercial advantages of Toughcrete & Toughcrete+ in flooring paving:
- Reduction of slab thickness upto 25% compared to plain concrete hence saving of concrete
- No hassles of installation of reinforcement hence saving of time and labour
- Direct saving in cost compared to the cost of steel for reinforcement
- Faster concrete pouring, especially with laser screed equipment
- Greater speed of spreading concrete hence saving of labour
- Longer service life of slabs, hence lower life cycle cost
Applications of Toughcrete & Toughcrete+ in flooring paving:
- Floorings of warehouses
- Floorings of container yards and stockyards
- Floorings of all kinds of factories
- Floorings of parking areas and driveways of residential as well as commercial buildings
- Airport runways and taxiways
- Pavements of highways and city roads
- Arterial roads in rural areas
- Foot paths in cities

Usual practice deliberates on welded wire fabric reinforcement within a single pane of a floor slab. Fabric does little to strengthen the external surface break off in fragments, which is common at the joints and edges. The primary function of welded wire fabric is to hold the floor slab together after the first small hairlines cracks have propagated to larger fractures. This serves to maintain some degree of "structural integrity". Whereas steel fibre reinforced concrete maintain “material integrity”.
Now what is structural and Material integrity???
Structural Integrity – The ability of a structure (consists many other components) to hold together under heavy load without breaking or bending excessively.
Material integrity – In this an engineer first considers materials mechanical properties such as strength, weight, toughness, elasticity and then depending on that determines the required size and shape of the structure so that it can hold heavy loads for longer life.
Typical areas of Steel Fibre reinforced concrete (SFRC) application include
Industrial ground floor slabs - Factories, Aircraft Hangers, Runways, Warehouses, Roads, Bridge Decks, Parking Areas, Dams and stabilization, Aprons and Taxiways, Commercial and Residential Slabs, Piling, Shot Crete, Tunnels.
