Mac 330

Macro 330 Synthetic Fibers

Like the placement of steel reinforcement, macro synthetic fibers can be placed in concrete to transfer post-crack stress, reduce crack widths, increase impact/abrasion resistance and generally improve the long-term performance of the slabs and walls. Macro synthetic fibers eliminates the need for welded-wire mesh (WWM) and small diameter reinforcing bars used as secondary reinforcement, depending on the application.

• The use of float pans on ride-on or walk behind machines are highly recommended as they enhance the finishability of concrete surface.
• Float pans should be used until noticeable resistance is observed with the finishing machine.
• A final pass with finishing blades should occur after pan removal.
• Finishing blades should be kept as flat as possible before increasing the tilt angle of the blades.
