Fibermesh - Model 650 -Synthetic Fiber

• Requires no minimum amount of concrete cover
• Is always uniformly positioned in the concrete and in compliance with codes
• Safe and easier to use than traditional reinforcement
• Saves time and hassle

• Graded macro-synthetic fiber for concrete secondary reinforcement used as an alternate to welded wire reinforcement and light rebar
• Inhibits the formation of plastic shrinkage and plastic settlement cracking
• Provides impact, abrasion and shatter resistance
• Greater surface area provides increased flexural toughness (residual strength)
• Improved ductility
• Provides improved durability
• Control of drying shrinkage and temperature cracking
• Good finishing characteristics
• Pumpable reinforcement

• Slabs-on-ground
• Sidewalks/Driveways
• Parking areas
• Overlays & toppings
• Exterior pavements
• Non-magnetic applications
• Shotcrete
• Composite metal decks

• Absorption : Ni
• Specific Gravity : 0.91
• Fiber Length* : Graded
• Electrical Conductivity : Low
• Melt Point : 324°F(162°C)
• Acid & Salt Resistance : High
• Aspect Ratio : 96.5

Product Use
Mixing Designs And Procedures: Fibermesh® 650 reinforcing is a mechanical, not a chemical process. Due to fiber efficiency, minor mix design modifications may be required depending on the application. Consult your Propex Concrete Systems representative for recommendations. Fibermesh 650 macro-synthetic fiber is added to the mixer before, during or after batching the other concrete materials. Mixing time of at least 5 minutes at mixing speed is required as specified in ASTM C 94.

Finishing: Fibermesh 650 reinforced concrete can be finished with normal finishing techniques in accordance with ACI 304, Section C.3.

Application Rate: The minimum application rate for Fibermesh 650 macro-synthetic fiber is 3.0 lbs per cubic yard (1.8 kg per cubic meter) of concrete. For Shotcrete or specialty concrete performance consult your Propex Concrete Systems representative for specific dosage recommendations.

Guidelines
Fibermesh 650 macro-synthetic fibers should not be used to replace structural reinforcement. Fibermesh 650 fibers should not be used as a means of using thinner concrete sections than original design. For joint spacing, follow industry standard guidelines suggested by PCA and ACL

Compatibility
Fibermesh 650 is compatible with all commonly used concrete admixtures and performance enhancing chemicals.

Packaging
Fibermesh 650 macro-synthetic fibers are available in 1.5 lb toss-in degradable bags. Bags are packed into cartons, shrink wrapped and palletized for protection during shipping.
