PDFPrint
CS-1000 Steel Fibers are made of low carbon, cut sheet steel with a tensile strength from 50 to 100 ksi. They contain deformations that run down the fibers and give an incredible mechanical bond to the concrete matrix. The CS-1000 fibers provide a uniform distribution of reinforcement throughout the concrete that increases the tensile strength, impact resistance, shear strength, and ductility of the concrete. Complies with ASTM C 1116, Type I Steel Fiber- Reinforce Concrete or Shotcrete and ASTM A 820, Type II, cut sheet.

CUT SHEET STEEL FIBERS

 

Guidelines

 

CS-1000 Steel Fibers are intended for crack containment reinforcement as outlined in ACI 360-10 3.2.2 and should not be used to replace primary reinforcement (structural or load bear- ing) as outlined in ACI 318. CS-1000 Steel Fibers should not be used to decrease the thickness of the concrete or increase the control joint spac- ing beyond the recommendations of ACI or PCA standard guidelines. We recommend following ACI guidelines for control joint locations and details. The standard dosage rates for CS-1000 Steel Fibers range from 30 lbs. to 60 lbs. per cubic yard of concrete. Packaging is 50 lb. boxes. Please consult DE Fiberworks for dosage rates for your application, design information, or more details when using CS-1000 Steel Fibers.

 

Applications

 

CS-1000 Steel Fibers may be used in any concrete application that requires increased crack control, improved impact, shatter and abrasion resistance, and improved durability. CS-1000 Steel Fibers can be used for the following applications:

 

Slabs-on-Ground

Industrial Floors

Warehouse Floors

Recycling Scrap Yards

Composite Metal Deck Slabs

Parking Areas

Equipment Foundations

Shotcrete

Mixing, Placing & Finishing

 

Mixing – CS-1000 steel fibers are packaged in pre-measured 50 lb. boxes and designed to be open and steel fiber introduced into the concrete mix during or after batching other concrete materials. Care should be taken to make sure the fibers are not added to the tail end of a high slump mix. Mixing should conform to ASTM C 94 with a minimum of 75 revolutions of the drum at full mixing speed to ensure uniform distribution of the fibers.

Placing – CS-1000 steel fibers can be pumped and placed using conventional equipment. Hand screeds can be used, but vibratory and laser screeds are recommended to minimize any surface fibers. At higher dosage rate of fibers, the use of a mid-range or high-range water reducer should be considered.

Finishing -Standard finishing equipment and techniques can be used when working with CS-1000 steel fibers. Finishing operations should begin as outlined in ACI 302. Troweling blades should be kept flat for as long as possible to ensure a fiber free surface.

 

 

Reinforcement Objective

 

Provide excellent crack-containment, impact and abrasion resistance. Enhance concrete durability and tensile strength.

Provide increased level of residual strength and flexural toughness. Alternate to WWF and rebar for shrinkage & temperature reinforcement.

Did You Know?

Concrete is widely recognized as an extremely versatile, cost-effective construction material?

 

Concrete is widely recognized as an extremely versatile, cost-effective construction material. Yet it is also beset with some drawbacks that are inherent to its composition.  By generally accepted engineering standards, concrete is relatively brittle and lacks ductility.  Intertwined with these problems is concrete’s propensity to crack in both its plastic (early-age) and hardened (long-term) state.  Early-age cracks are microscopic fissures caused by the intrinsic stresses created when the concrete settles and shrinks over the first 24 hours after being placed.  Long-term cracking is in part caused by the drying shrinkage that transpires over time.  In either case, these cracks can jeopardize the overall integrity of the concrete and not allow it to maintain – or possibly ever attain – its maximum performance capability.

 

This is the basic reason reinforcement in concrete is required.  Irregular cracks are unsightly and difficult to maintain but generally do not affect the integrity of the concrete.  Joints in concrete slabs are simply pre-planned cracks that are created by forming, sawing, or tooling.  Concrete slabs that are designed for serviceability typically use reinforcement such as deformed reinforcing steel bars (rebar) or welded wire fabric (WWF) to hold cracks tight.  The primary function for the reinforcement is to maintain aggregate interlock for load transfer and improve joint stability.  Rebar and WWR do not inhibit the formation of cracks, but if properly positioned provide reinforcement once a crack has developed.  Fiber reinforcement can provide the same function, is distributed throughout the cross-section of the concrete and distributes the stresses attributed to shrinkage throughout the panel making the joints much more stable. This distribution of fibers provides a totally reinforced cross-section of concrete and changes the way the concrete works.
