STRUX® 75/32

Synthetic Macro Fiber

Description

STRUX® 75/32 fiber is a synthetic macro fiber complying with ASTM C1116/C1116M Type III, which can be used in ready-mixed concrete for different applications such slab-on-ground flooring, composite steel floor deck assemblies, topping slabs, thin-walled precast overlays and pavements.  Unlike traditional microfiber reinforcement, STRUX® 75/32 macro fibers are specifically engineered to provide post-crack control performance.

STRUX® 75/32 macro fibers are extruded from a virgin polypropylene and polyethylene polymer blend.

The geometry, strength and high modulus is specifically engineered to provide high post-crack control performance with excellent dispersion into the concrete matrix, reducing plastic and hardened concrete shrinkage cracking, and increasing fatigue resistance and concrete toughness. STRUX® 75/32 macro fibers have been specifically engineered to be a user-friendly fiber reinforcement to replace welded wire reinforcement, steel fibers and light rebar reinforcement. STRUX® 75/32 macro fibers are easier and safer to use, compared to these other types of reinforcement.

Application areas

STRUX® 75/32 macro fibers may be used in a variety of ready mix and precast applications including:

  • Residential and commercial slab-on-ground flooring,
  • Thin and conventional whitetoppings and overlays, pavements, composite steel deck floor assemblies, and thin-walled precast elements (septic tanks, vaults, walls, etc.).

Benefits

  • Can be used to completely or partially replace light rebar, welded wire reinforcement and steel fibers.
  • Easy to mix and fast to disperse.
  • Barely visible on the surface obtaining highly aesthetic concrete.
  • Saves money through reduction or elimination of steel labor and material transportation, delivery and jobsite storage, and fewer construction days.
  • Enhances safety by eliminating handling of steel fibers, welded wire reinforcement and rebar.
  • Enhances jobsite safety by eliminating tripping hazards commonly associated with welded wire fabrics and light rebar.
  • Eliminates concerns of proper positioning of reinforcement.
  • Due to unique fiber design and uniform three dimensional dispersion, both plastic as well as drying shrinkage cracking is reduced, improving the ductility and durability of the concrete.
  • Provides superior crack control due to the geometry and elastic modulus, corrosion resistant properties (non-ferric).
  • Ease of pumping, passes easily through pump grates.
  • May be used to provide effective crack width control.
  • Reduces shotcrete rebound and improves cohesion.
