STRUX® Macro Synthetic Fibers

A Replacement for Welded Wire Mesh

Welded wire mesh has long been used to reinforce slab-on-ground concrete, bridge decks and thin-walled precast applications for temperature and shrinkage crack control. Although mesh provides adequate performance, it adds many downsides. The mesh takes time to transport, install and correctly chair.

STRUX® Macro Fibers improve impact resistance, durability and long-term crack control properties of concrete by equally distributing structural fibers throughout the entire concrete matrix. STRUX® eliminate the risk of corrosion, as well as the risk or job site obstruction inherent with the use of welded wire or mild steel reinforcement. STRUX® reduces construction time and labor costs by replacing welded wire mesh (WWM).  STRUX® can be used to replace non-structural steel for slab on ground, precast elements, elevated decks and tunnel liners.

Fibers

STRUX® 75/32

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.

STRUX® 85/50

STRUX® 85/50 synthetic macro fibers are a unique form of high strength, high modulus synthetic macro reinforcement that is evenly distributed throughout the concrete matrix. It consists of synthetic macro fibers 50 mm (2 in.) in length with an aspect ratio of 85 that have specifically been designed to ensure ease of use and rapid dispersion in concrete. STRUX® 85/50 is used in concrete to improve the material properties including toughness (post crack energy absorption), impact and fatigue resistance, residual strength and durability.
Fibers

STRUX® 90/40

STRUX® 90/40 synthetic macro fibers are a unique form of high strength, high modulus synthetic reinforcement that is evenly distributed throughout the concrete matrix. The macro fibers add toughness, impact and fatigue resistance to concrete and improve residual strength and durability. Unlike traditional microfiber reinforcement, STRUX® 90/40 macro fibers are specifically engineered to provide post-crack control performance. Reinforced concrete with STRUX® 90/40 macro fibers has been shown to reliably achieve residual flexural strength values in excess of 150 psi (1 MPa) at dosages that can easily be batched and finished. STRUX® 90/40 macro fibers are 1.55 in. (40 mm) in length with an aspect ratio of 90 and have specifically been designed to replace welded wire reinforcement, steel fibers and light rebar reinforcement. STRUX® 90/40 macro fibers are a user-friendly fiber reinforcement, which are easier and safer to use, compared to these other types of reinforcement. TRUX® 90/40 macro fibers may be used in a variety of ready mix, precast and shotcrete applications including slab-on-ground flooring, overlays, pavements, bridge decks, composite steel floor deck assemblies, mass concrete, thin-walled precast elements (septic tanks, vaults, walls, etc.), tunnel linings, pool construction and slope stabilization.

STRUX® BT50

STRUX® BT50 synthetic macro fiber reinforcement is a high strength, high modulus synthetic macro reinforcement that imparts toughness, impact and fatigue properties to concrete. STRUX® BT50 is a patented engineered design providing superior post-crack control performance with a broad range of applications. STRUX® BT50 Synthetic Macro Fiber reinforced concrete reliably achieves residual strength values in excess of 145 psi for every 4.5 lbs/yd3 (1 MPa for every 2.7 kg/m3). STRUX® BT50 fibers are 2 in. (50 mm) in length with an aspect ratio of 75 and are primarily designed to replace steel fibers, welded wire fabric, light rebar and other select secondary reinforcement. STRUX® BT50 is a user friendly fiber reinforcement which is easier and safer to use, compared to other types of reinforcement.

The Benefits of Using STRUX® Macro Fibers

Shave Off Time from Construction Projects

In today’s market, schedule is everything. Transporting, placing, and chairing welded wire mesh adds time to any project. STRUX® eliminates all that time—and its material characteristics make it as strong, if not stronger, than the alternative.

Add Toughness to Concrete with Less Material

STRUX® fibers add toughness, impact, and fatigue resistance to concrete. As opposed to microfiber reinforcement, STRUX® Macro Fibers add post-crack control performance. STRUX® allows users to save on material by decreasing thickness of slab on grade or overlays. For designers, this increases the range of possible forms. For contractors, this means less material overall may be needed. STRUX® reduces the time required for the critical path resulting in faster construction times and earlier delivery of the building for the contractor.

Technical Advice Backed by Experience
