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.
