The Latest Composite Technology

The DUCON® Micro-Reinforced Concrete System is a proprietary, innovative system designed for extreme load resistance and energy absorption.

DUCON® Micro-Reinforced Concrete Systems

DUCON® is an innovative, high-performance strengthening and force protection system designed for extreme load resistance and energy absorption. DUCON® combines an infuseable ultra high-performance grout with a densely layered MicroMat® steel reinforcement system. The highly-engineered and test-proven system can be custom-designed to a project’s specific performance requirements.
 

“Moldable Steel”

Placement characteristics similar to concrete, combined with the ductility and energy absorption properties of steel, give DUCON® “moldable, steel-like” characteristics.

  • Like concrete in placement versatility, DUCON® can be applied to new and existing structural members, or prefabricated off-site to create a wide range of precast shapes and sizes.
  • Like steel with its ductility and energy dissipating qualities, the DUCON® system allows for the highest level of performance for the most challenging applications.

Specific uses:
  • Moldable Steel
    Force Protection
  • Flexural and shear upgrade of beams and slabs
  • Axial strengthening and confinement of columns
  • Seismic retrofit of columns
  • Thin structural overlays
  • Lightweight architectural façade panels




     
Advantages:
  • Micro-Reinforced Concrete Systems
    Ability to adjust the design and physical properties to meet project requirements
  • High-performance properties versus thickness ratio (i.e. thin strengthening layer)
  • Can be applied in thicknesses as thin as ½”
  • Ease of constructability allows use in a wide variety of design requirements, geometries, and orientations
  • Flexibility in application methods (both in-situ and precast)
  • Extremely ductile
  • Abrasion resistant
