HPS-950

PDFPrint
HPS-950 Blended Macro/Micro fibers system incorporates the second generation of macro fibers. They are made of High Performance co-polymer macro fibers blended with 100% virgin polypropylene micro fibers. HPS-950 fibers are Engineered and Manufactured to exceed the requirements of ASTM C 1116 “Standard Specification for Fiber-Reinforced Concrete and Shotcrete”, Type III Synthetic Fiber-Reinforced Concrete. HPS-950 fibers are manufactured to the requirements of the International Building Codes. The high modulus, high strength fibers are distributed throughout the concrete to provide excellent crack control and add toughness.

HPS-950

 

HIGH-PERFORMANCE SYNTHETICS

 

Guidelines

 

HPS-950 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 bearing) asoutlined in ACI 318. HPS-950 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 950 is 5 lbs. per cubic yard of concrete. Please consult DE Fiberworks for dosage rates for your application, design information, or more details when using HPS-950 blended fibers.

 

Applications

 

HPS-950 blended fibers may be used in any concrete application that requires increased crack control, improved impact, shatter and abrasion resistance, and improved durability. HPS-950 fibers are extremely easy to finish and are ideal for the following applications:

 

Slabs-on-Ground

Exterior Paving

Concrete Overlays & Toppings

Industrial Floors

Commercial Floors

Warehouse Floors

Sidewalks/Driveways

Parking Areas

Non-magnetic applications

Mixing, Placing & Finishing

Mixing – HPS-950 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-950 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-950 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

 

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.

In the U.S., synthetic and steel fibers have been used in concrete for over 30 years to improve concrete’s plastic (early-age) and hardened properties.  Micro-synthetic fibers have been used to provide control of random plastic-shrinkage cracking.  Steel fiber and Macro-synthetic fibers have been used to provide crack width control in concrete after it reaches a hardened state.  Combining these products (Blends) provides plastic and hardened state benefits.  The concrete applications that fiber reinforcement is used and includes, but not limited to, slabs-on-grade, composite metal deck slabs, topping slabs over precast panels, precast, and shotcrete.
