A report on the synthetic fiber reinforced conccrete

Friday, 19 January Most of the products and technologies here will be exhibited at World of Concrete. MasterFiber series includes six macrofiber MAC designation and five microfiber F, fibrillated; M, monofilament offerings.

MAC 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 for secondary reinforcement and plastic shrinkage control; MAC Plus for secondary reinforcement against cracking; MAC CB, chemically-enhanced to impart superior bonding and increase structural capacity and toughness; and, CB 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; Fan enhanced fibrillated polypropylene product geared for shrinkage and temperature reinforcement; Ma 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.

Steel Pro T5 Company has full line of FiberForce micro and macro synthetic products— monofilament or fibrillated—plus synthetic fiber blends and steel fibers for concrete reinforcement. Monofilament microsynthetic fibers are Ny-Pro and Ny-Tuf fine and standard denier monofilament nylon; and, FiberForce and ultra-thin and standard monofilament polypropylene.

Fibrillated microsynthetic fibers are FiberForce standard grade and high fiber count.

FiberForce macrosynthetic fibers are the flagship Macro Pro, a highly modified fibrillated polyolefin resin blended product; Performance Plus DOT, approved by state departments of transportation;an embossed tape product for cast-in-place applications; and, HP, whose unique profile maximizes mechanical bonding.

Company also offers macrosynthetic and microsynthetic fiber blends that provide both post-first crack reinforcement and plastic shrinkage crack and drying shrinkage crack reinforcement.

Typical blends are 4: Leading the macro-micro blends is FiberForce In addition to polypropylene, polyolefin and nylon fibers, ABC offers two grades of FiberForce steel products: T1 and T5 cold drawn steel wire and cold drawn shave.

Tuf-Strand Fibers can be used as an equivalent reinforcing option to steel fibers, wire mesh and light gage reinforcing bars in precast concrete, slabs on grade, composite steel decks and shotcrete. Tuf-Strand SF is UL certified for composite steel deck construction and specified for replacement of limited structural steel in precast, slabs on ground, pavements and shotcrete.

Available in various sizes and lengths of monofilament and fibrillated polypropylene, monofilament polyester and nylon, PSI Fiberstrand is used for plastic shrinkage crack control and suited to secondary reinforcing for slabs and precast.

A proprietary parallel packaging system aligns all the fibers to ensure proper distribution in the concrete mix, and yields a compact bag to provide the lowest possible product freight and storage costs. A division of Great Lakes Polymer Technologies, Fabpro cites plus years as a full-line source of macrosynthetic, microsynthetic monofilament and fibrillated and steel fibers, plus blends, to make good concrete better at a lower overall cost.

The newest additions to a full line of synthetic fibers for cast-in-place and precast concrete include Enduro Prime and Enduro Mirage. Ferro, the most popular offering, is a macro synthetic fiber used to reduce plastic and hardened concrete shrinkage, improve impact strength, increase fatigue resistance and toughness.

Its twisted bundle technology combines standard fibrillated polypropylene fiber and heavy-duty monofilament with a strong synthetic copolymer.

Ferro is pre-blended and typically used in 1. Econo-Mono is a homopolymer polypropylene micro monofilament fibrous reinforcement offering long-term durability for a variety of applications.

Used in conjunction with steel, it is intended to reduce the formation of shrinkage cracks prior to initial set and reduce settlement shrinkage.

Econo-Mono is typically used in 0. Super-Net is a homopolymer polypropylene micro fibrillated fibrous reinforcement in a collated fibrillated network form.

Super-Net is typically used in 0. 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. 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.

Historically, steel fiber blends utilize synthetic microfibers to reduce plastic shrinkage cracking. The UltraFiber 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 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 reduces plastic and temperature shrinkage, and has no negative effect on color, finishing, or appearance of the concrete.The Memphis District contracted with the U.

S. Army Engineer Research and Development Centers (ERDCs) Concrete and Materials Branch (CMB) to proportion three fiber-reinforced concrete mixtures containing 3-, 2-, and 1-lb/yd3, respectively, of synthetic (polypropylene) fiber into the current mixture proportion used at Richardson .

Concrete with Synthetic Fibers, January APPLICATION GUIDELINES Do Use Synthetic Fibers For: • The reduction of concrete cracking as a result of plastic shrinkage. • An alternate system of nonstructural secondary and/or temperature reinforcement.

• Greater impact, abrasion, and shatter resistance in concrete.

Fibers include steel fibers, glass fibers, synthetic fibers and natural fibers – each of which lend varying properties to the concrete.

In addition, the character of fiber-reinforced concrete changes with varying concretes, fiber materials, geometries, distribution, orientation, and densities.
