Fiber Concrete Mixes

Fiber Concrete Mixes

Particularly useful on surfaces that curve or slope, fiber reinforcement can also reduce the permeability of concrete and thus reduce the bleeding of water that delays construction and impairs bonding between poured layers. Because we mix your concrete on the job site as needed, our trucks can supply the exact amounts you need to conform to the specific tolerances you require, without wasting time, materials, or money.

Common Fiber Concrete Projects:

  • Runway, Aircraft Parking, and Pavements
  • Tunnel Lining and Slope Stabilization
  • Blast Resistant Structures
  • Thin Shell, Walls, Pipes, and Manholes
  • Dams and Hydraulic Structures
  • Bridges and Overpasses

Frequently Asked Questions about Fiber Concrete Mixes

When concrete is first placed, moisture will evaporate from the surface faster than from within the mass of the concrete. This causes the surface to cure faster than the concrete below the surface, which in turn causes tensile stresses build up and shallow microscopic cracks develop in random directions. If allowed to develop without restraint, these cracks can grow wider and lengthen to become major aesthetic and functional problems. Cracks also occur due to excessive flexural stresses brought on by bending when spanning distances. Fiber reinforcing helps to restrict the initial shrinkage cracking that occurs in the initial stages and improves the concrete’s overall longevity.

Several types of fiber exist, including steel, glass, synthetic, and natural fibers, and the composition that would be best for a particular job depends on the usage and environment of the finished slab. In addition to reducing the cracking that can result from uneven moisture evaporation, fiber reinforcing can improve freeze-thaw resistance, impact resistance, structural strength, or ductility, depending upon the specific composition of the fibers. Fiber reinforcing has no impact on the air content of concrete, but will have a significant impact on slump.

One common concern when working with fiber reinforced concrete is the slump, or consistency of the concrete from one truckload to the next. This can be affected by the type of fiber used, the quantity of the fibers, the length of the fibers, the proportions, and the other additive incorporated into the mix. Because we mix your specific concrete components on site as needed, we can ensure that each load has precisely the same composition and consistency.
