Why PrīmXComposite

Steel Fiber-Reinforced, No Shrink Industrial Floor System

PrimXComposite Floor compairison

PrīmXComposite (pronounced prime x composite) is the first steel fiber-reinforced, shrink-compensating industrial concrete floor system. PrīmXComposite uses steel fibers and proprietary additive mixtures, combined with ready-mix concrete to form a composite material. Up to 60 percent thinner than traditional concrete, PrīmXComposite has much higher load-bearing capacity. Due to the lack of shrinkage and high steel fiber content, PrīmXComposite eliminates saw cuts and issues caused by joints.

PrīmXComposite form a micro-composite structure, including growth of crystals

During the initial wet-cure, the PrīmXComposite absorbs water causing a delayed chemical reaction. The additives in PrīmXComposite form a micro-composite structure, including growth of crystals expanding the internal concrete matrix under intense pressure. This puts the steel fibers in tension and the concrete matrix in a permanent pre-stress compression, creating incredible strength and performance from a thinner profile.

PrīmXComposite’s proprietary system is site-added by trained, exclusive licensees of the technology under a strict quality control regimen.

Beyond its stability, PrīmXComposite can contribute to earning LEED points and has sustainability benefits. It uses less cement, eliminating thousands of tons of Co2 emissions per project.  It also eliminates silica dust from saw cutting.



Concrete History

Concrete Joints

Advancements in composite materials, such as aluminum, carbon fiber, Kevlar, plastics and polymers create thinner materials that are lighter with increased strength and performance. While other materials have been improved, concrete has been virtually unchanged since the early 1820s. Traditional concrete:

  • Is strong in compression, but weak in tension
  • Is considered a quasi-brittle material, a brittle ceramic
  • Needs to be cut in anticipation of cracks, sawing joints every 12 to 16 feet
    (3,64 to 4,87 meters)
  • Requires steel rebar for reinforcement
  • Curls at joints, causing deterioration and reducing productivity
  • Requires regular maintenance and high repair costs
