PIONEER® HTM® Twist -Twisted bundle macro fiber
Overview
PIONEER®HTM® Twist is an advanced twisted monofilament macro synthetic fiber designed to enhance the durability and structural performance of fiber-reinforced concrete. Made from 100% virgin polypropylene, it creates a three-dimensional reinforcement network within concrete, offering superior crack resistance, toughness, and flexibility. It is a versatile, eco-friendly alternative to traditional steel fibers, welded wire mesh, and other reinforcement materials.
Key Benefits
-
Superior Performance: Enhances crack resistance during both the plastic and hardening phases, improving long-term durability.
-
Cost-Effective and Time-Saving: Eliminates the need for cutting, placing, and tying steel reinforcements, reducing construction time and labor costs.
-
Safe and Corrosion-Free: Unlike steel fibers, it doesn’t corrode or degrade in aggressive environments, maintaining structural integrity over time.
-
Improved Concrete Aesthetics: Its uniform dispersion minimizes surface visibility, ensuring smooth and visually appealing finishes.
Product Description
PIONEER® HTM® Twist is a macro synthetic fiber complying with ASTM C1116, Type III. It features a twisted monofilament design made from 100% virgin polypropylene. The geometry, strength, and high modulus are specifically engineered , PIONEER® HTM® Twist provides a uniform three-dimensional reinforcement system for concrete mixtures. It can replace traditional steel mesh and steel fibers, reducing both plastic and hardened stage cracking in concrete while enhancing fatigue resistance and flexural toughness. The very heavy-duty twisted-bundle design of PIONEER® HTM® Twist improves load transfer and performance after cracking, offering a higher level of reinforcement replacement compared to standard macro synthetic fibers.
PIONEER® is a leading brand in the engineering fiber industry with a 22-year history. Its fiber-reinforced concrete technology has been awarded the China National Science and Technology Progress Award. The PIONEER® product line includes four main series: HPM® Micro Fibers, HTM® Macro Fibers, HGM® Asphalt Fibers, and PNE® Steel Fibers. These products have been successfully applied in thousands of major projects worldwide and are highly regarded in the civil engineering field.
