HPS 650

PDFPrint
HPS-650 fibers are High-Performance Synthetic Macro Fibers that are manufac- tured from 100% virgin co-polymer resin and exceed the requirements of ASTM C 1116 “Standard Specification for Fiber-Reinforced Concrete and Shotcrete”, Type III Synthetic Fiber-Reinforced Concrete. HPS-650 fibers are manufactured to the requirements of the International Building Codes. HPS-650 fibers are specifically engineered for crack containment and help control plastic shrinkage cracking. HPS-650 fibers provide long-term durability, fatigue resistance as well as concrete toughness.

Description

 

 HPS-650

HIGH-PERFORMANCE SYNTHETICS

 

Guidelines

 

HPS-650 fibers are intended for secondary reinforcement as outlined in ACI 360-10 3.2.2 and should not be used to replace primary reinforcement (structural or load bearing) as outlined in ACI 318. HPS-650 fibers should not be used to decrease the thickness of the concrete or increase the control joint spacing beyond the recommendations of ACI or PCA standard guidelines. We recommend following ACI guidelines for control joint locations and details. The standard dosage rate for HPS-650 fibers is 3 to 5 lbs. per cubic yard of concrete depending upon the application and project requirements. Please consult DE Fiberworks for dosage rates for your application, design information, or more details when using HPS-650 fibers.

 

Applications

 

HPS-650 fibers may be used in any concrete application that requires increased crack control needs. These fibers are ideal in the following applications:

Slabs-on-Ground

Composite Metal Decks

Overlays & Toppings

Commercial Floors

Commercial Floors

Shotcrete

Sidewalks/Driveways

Parking Areas

Exterior Pavements

Non-magnetic applications

HIGH-PERFORMANCE SYNTHETICS

 

UL Classified: Type HPS-650 fibers. For use as an alternate or in addition to the welded wire fabric used in Floor-Ceiling D700, D800 Series Designs. Fibers added to concrete mix at a rate up to maximum of 5.0 lb. of fiber for each cubic yard of concrete.

 

 

 

Reinforcement Objective

 

To inhibit plastic and settlement shrinkage cracking prior to the initial set, and to reduce hardened concrete shrinkage cracking, improve impact and abrasion resistance, and enhance concrete durability. Provide increased level of residual strength and flexural toughness. Alternate to WWF and rebar for shrinkage & temperature reinforcement.

 

Mixing, Placing & Finishing

 

Mixing – HPS-650 fibers are packaged in pre-measured water soluble bags designed to be introduced into the concrete mix before, 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 – HPS-650 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 HPS-650 fibers. Finishing operations should begin as outlined in ACI 302. Troweling blades should be kept flat for as long as possible to help minimize the fibers on the surface.

Fiber reinforcement makes good concrete better?

 

Fiber reinforcement makes good concrete better, in short because fiber reduces cracking and adds long-term durability to a wide variety of concrete applications.  Fiber reinforcement provides an alternative construction method to traditional welded wire fabric and rebar reinforcement and provides additional benefits, including guaranteed 3-dimensional reinforcement, safer installation and more economical.  DE Fiberworks supply a full range of fiber reinforcement products to meet challenging demands and provide the best fiber reinforcement solution for the specific application.   Fiber technology has advanced over the last decade to improve mixing, finishing and performance in fresh and hardened concrete.
