Concrete Products examines polypropylene, nylon, acrylic and other synthetic products for secondary concrete reinforcement, plus steel fibers, which continue to show potential for replacing conventional rebar or mesh. Most of the products and technologies here will be exhibited at 2018 World of Concrete.



An alternative to concrete-grade rope or tape-type synthetics, MasterFiber MAC 360 FF is engineered to replace welded-wire reinforcement and small diameter steel bar.

MasterFiber series includes six macrofiber (MAC designation) and five microfiber (F, fibrillated; M, monofilament) offerings. The newest is MAC 360 FF, manufactured from a proprietary blend of polypropylene resins and equal to ASTM C1116/C1116M Standard Specification for Fiber-Reinforced Concrete guidelines. The synthetic hybrid fiber was developed to meet contractor, producer and engineer performance targets; strengthen plastic concrete to minimize shrinkage and settlement cracking; and, augment hardened slabs and structures’ post-crack flexural toughness.

MAC 360 FF serves as a noncorrosive, three-dimensional, secondary reinforcement alternative to conventional welded-wire reinforcement, small diameter bars and steel fibers. Along with providing effective crack and plastic shrinkage control and reducing settlement cracking, the new fiber effectively increases the post-crack residual strength of concrete, plus impact and shatter resistance. The fiber suits hand-troweled concrete; industrial, warehouse, commercial and residential slabs on grade; pavements, white-topping and overlays; composite metal decks; and, architectural panels.

Rounding out the MasterFiber macrosynthetic offerings are MAC Matrix, engineered for secondary reinforcement to control shrinkage, temperature and settlement cracking; MAC 100 for secondary reinforcement and plastic shrinkage control; MAC 100 Plus for secondary reinforcement against cracking; MAC 2200 CB, chemically-enhanced to impart superior bonding and increase structural capacity and toughness; and, 160CB with chemical bonding capability for shotcrete, precast tunnel segments and concrete pipe.

MasterFiber microfibers are F 70, a fibrillated product for shrinkage and temperature reinforcement; F 100, an enhanced fibrillated polypropylene product geared for shrinkage and temperature reinforcement; M 100, a high-tensile strength, high modulus of elasticity, ultra-thin monofilament homopolymer polypropylene product; plus, M 35 and M 70, monofilament polypropylene fibers engineered to reduce plastic shrinkage cracking. — BASF Construction Chemicals/Admixture Systems, 800/628-9990;

Sinta F

Strux macrofiber

Strux is the newest addition to a full synthetic fiber offering, recently rebranded Sinta. A synthetic structural macrofiber providing high-strength reinforcement for resisting and controlling temperature and shrinkage cracking in concrete, it can substantially speed up construction time by eliminating the need to install welded wire fabric (WWF) or light rebar at the worksite. Compared to WWF, GCP engineers contend, applications using Strux fibers can be completed faster and exhibit long-term durability at lower installed costs—with estimated savings of 20 to 30 percent. Applications include floors, elevated composite metal decks, soil-supported slabs, pavements, tunnel liners and thin-walled precast.

Sinta succeeds Grace Fibers, Grace Microfibers and Gilco Fiber brands, and spans Sinta F (fibrillated), Sinta M (monofilament) and Sinta FDS (fluid delivery system) synthetic microfibers for concrete. The microfibers suit applications where designers, contractors or producers aim to minimize cracking due to the rapid surface drying of plastic concrete. The use of Sinta microfibers in the mix protects concrete from stresses that cause cracking, thus improving overall quality and durability. The fibers perform in slabs on grade, pavements, overlays, sloped walls, pools, shotcrete, stucco, tunnels, precast, and precast/prestressed products. — GCP Applied Technologies, Cambridge, Mass., 617/876-1400;

Solomon Colors

Steel and microfiber blends provide a unique synergy, improving hardened concrete performance while reducing plastic shrinkage. Historically, steel fiber blends utilize synthetic microfibers to reduce plastic shrinkage cracking. The UltraFiber 302 combination effectively creates an alternative to welded wire fabric in several applications, and improves on conventional blends by replacing synthetic fibers with natural cellulose.

The UltraFiber 500 cellulose microfiber meets or exceeds polypropylene fiber performance characteristics, company engineers contend. When blended with steel fiber, the result is higher impact and abrasion resistance. In addition, the UltraFiber 302 reduces plastic and temperature shrinkage, and has no negative effect on color, finishing, or appearance of the concrete. The combination of steel and cellulose fibers is a natural form for improving early age and long-term performance.Solomon Colors Inc., Springfield, Ill., 800/624-0261, 217/522-3112;
