How Twisted Macro Fibers Enhance Fiber-Reinforced Concrete
Learn how PIONEER® HTM® Twist fibers improve crack control, toughness, and durability in heavy-duty concrete applications.
HTM® Twist macro synthetic fibers form a uniform, three-dimensional reinforcement network within fiber-reinforced concrete and shotcrete, effectively controlling plastic and drying shrinkage cracking. Their twisted bundle design increases bonding with the concrete matrix, providing enhanced impact, fatigue, and flexural resistance while replacing traditional welded wire mesh and steel fibers in many applications.
