Steel Fiber Concrete Slabs On Ground

The american concrete institute.

Steel fiber concrete slabs on ground. Founded in 1904 and headquartered in farmington hills michigan usa the american concrete institute is a leading authority and resource. It becomes evident that the structural performance involves more than stress analysis. In ordinary jointed floors steel fibers provide a safety net by limiting the width of any cracks that occur by accident between the joints. Since we needed a zero slump mix dispersion was difficult and adding water was necessary.

Steel fiber reinforced concrete ground slabs 3 3 ground slabs distresses since pavement performance is a time dependant the behaviour of materials cannot be predicted from stress analysis. Sikafiber is simply added during the concrete production and embedded in the cement paste matrix as the concrete is being placed. However if the cracks become wide enough to spall this can be major problem. An extensive experimental investigation with the aim of studying the structural behavior of slabs on ground made of steel fiber reinforced concrete sfrc is pr.

Sikafiber technology provides several opportunities to improve the fresh and hardened concrete properties in fiber reinforced concrete this is especially the case for ground bearing concrete slabs where sikafiber will enhance durability save time and money. Chapter 10 fiber reinforced concrete slabs on ground p. We even had to make heavy duty concrete pavers 4x4x8 nominal with steel fibers for heavy equipment repair and service shops for tacked equipment. Full scale ground slabs with variable matrix strengths 45 65 and 85 mpa were tested.

Steel fiber reinforcement for ground supported slabs cfs 100 2 fibers steel fibers can help control random cracks in ground supported concrete floors. If there is a sufficient quantity for a particular situation based on slab usage joint spacing concrete shrinkage potential etc the post crack load carrying ability of steel fibers can be very beneficial.

Next level concrete performance. Cfs steel fibers limit the width of any cracks that occur between the joints and to enhance aggregate interlock at the joints playing a role similar to that of wire mesh or light rebar in floor. The bents and hooks are crucial to the fiber s anchoring performance and subsequent concrete ductility these features in combination with steel elongation are the main differentiators of our dramix steel fiber concrete reinforcement series. Steel fiber reinforcement has been around since the 1970 ies and continues to evolve with time.
