    ​Macrofibers

    Synthetic Fibers for Concrete Reinforcement

    Macrofiber concrete reinforcement is achieved by adding macrofibers with superior bonding properties to the concrete matrix. The result is crack control and an extended service life of the concrete. Synthetic macrofibers are manufactured from a proprietary blend of polypropylene resins, in compliance with ASTM C 1116/C 1116M. They are specifically engineered for use as shrinkage and temperature (secondary) reinforcement and provide excellent plastic shrinkage control and reduced settlement cracking.
    • Improves green strength
    • Uniform distribution throughout the concrete mixture
    • Excellent finishability and post-first performance
