SFRC (Steel Fiber 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 the 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+(steel fiber) 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 the growth of the cracks. You can also check here other products available at Precision Drawell like concrete reinforcing fibers, SFRC concrete, steel fiber reinforcement and tunnel steel fiber.
Reinforced concrete slabsthough cost less than plain concrete slabs, have the disadvantage of the costly, laborious, time consuming and at times – the hazardous process of installation of reinforcement mesh. Steel Fiber in Flooring provides excellent resistance to reduce breaks in hardened concrete. Hence, SFRC (Steel Fiber Reinforced Concrete) slabs are the best, most scientific and long-lasting solution for all types of floorings and pavements.
So now looking more deeply that how Steel Fiber Reinforced Concrete is advantageous?
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 fiber reinforced concrete maintain “material integrity”.
