Shubham Polyspin’s waved macro fiber is a high-performance synthetic reinforcement solution designed for concrete and shotcrete applications. Complying with Standard Specifications for Fiber Reinforced Concrete and Shotcrete, this fiber is engineered to significantly reduce shrinkage cracking and improve post-crack performance.
Used at a typical dosage of 4 kg/m³, these waved macro fibers can reduce shrinkage cracking by up to 85% compared to plain concrete, while also enhancing toughness, ductility, and load-bearing capacity.
