​MasterFiber MAC 2200 CB

Synthetic macrofiber with chemical bond for low deflection applications

How does MasterFiber MAC 2200 CB work?

MasterFiber MAC 2200 CB product is a chemically enhanced synthetic macrofiber that exhibits superior bonding to cementitious matrices, thus increasing the post-crack load-carrying capacity and toughness of fiber-reinforced concrete. The superior performance of MasterFiber MAC 2200 CB product results from a novel polymer resin technology that provides engineered chemical bonding, a technology breakthrough from Master Builders Solutions. Through this advanced technology and a highly engineered fiber architecture, the bonding capabilities of MasterFiber MAC 2200 CB product far exceed that of the other commercially available polyolefin-based synthetic macrofibers.

Recommended uses:

• Cast-in-place and wet precast concrete
• Slab-on-ground
• Bridge decks
• Concrete pavements
• White topping and overlays

What are the unique features of MasterFiber MAC 2200 CB?

• Chemically enhanced to provide superior performance as compared to typical high performing synthetic macrofibers.
• Engineered for use as secondary reinforcement to control shrinkage and temperature cracking and to provide performance equivalent to that of other commercially available synthetic macrofibers, at a reduced dosage.
• Reduced dosage will result in improved handling properties in the fresh state, as well as, improved finishability.
• The unique packaging helps to promote even distribution and optimal dispersion of fibers in concrete mixtures.
• ​Created specifically to replace welded-wire reinforcement and No. 3 and No. 4 (10 mm and 13 mm) reinforcing bars that are typically used as temperature and shrinkage reinforcement.

What are the beneifts of MasterFiber MAC 2200 CB?

• Provides post-crack performance equal to that obtained with typical, commercially available synthetic macrofibers at a reduced dosage
• Improves placement and finishing characteristics compared to traditional synthetic macrofibers
• Eliminates the need for welded-wire reinforcement (WWR) and conventional steel bars as secondary reinforcement, depending on the application
• Utilizes an advanced packaging system that improves dispersion, reduces storage footprint and increases bags per pallet, thus optimizing pallet’s capacity
• Reduces construction time and overall labor and material costs​
