TW50 – 50mm Macro Polypropylene Fiber for Fiber-Reinforced Concrete

TW50 – High-Tensile Macro Mono-Filament Polypropylene Fiber

TW50 is a high-tensile macro mono-filament polypropylene fiber engineered for fiber-reinforced concrete (FRC) applications where performance matters. At 50mm in length, TW50 delivers structural-level reinforcement capable of replacing traditional welded wire mesh — reducing labour, eliminating corrosion risk, and simplifying your pour. Each bag contains 1kg, pre-packaged in a PE (polyethylene) bag for easy handling, accurate dosage, and clean job site management.

Technical Specifications

• Fiber Type: Macro Mono-Filament Polypropylene (Twisted)
• Fiber Length: 50mm
• Bag Weight: 1kg
• Packaging: PE (polyethylene) bag — easy to handle, dose, and store
• Classification: High-Tensile Synthetic Macro Fiber
• Standards Compliance: ASTM C-1116, Section 4.1.3 & ASTM C-1399

Primary Benefits

• Shrinkage crack control: Effectively controls plastic and drying shrinkage cracking
• Thermal crack control: Resists cracking caused by temperature differentials during cure and service
• Increased tensile strength: Significantly improves the tensile capacity of concrete
• Increased flexural strength: Enhances post-crack flexural performance
• Welded wire mesh replacement: Provides sufficient reinforcement to replace WWM in many slab and pavement applications
• 1kg PE bag: Pre-dosed for easy manipulation and accurate dosing on the job site
• Non-corrosive, non-magnetic, alkali-resistant

Typical Applications

• Industrial and commercial slabs-on-grade
• Precast concrete elements
• Shotcrete and sprayed concrete
• Pavements and hardstands
• Tilt-up panels
• Any FRC application requiring mesh replacement

Standards & Compliance

TW50 meets the requirements of ASTM C-1116, Section 4.1.3 (Standard Specification for Fiber-Reinforced Concrete) and ASTM C-1399 (Standard Test Method for Obtaining Average Residual-Strength of Fiber-Reinforced Concrete).

Frequently Asked Questions

Can TW50 replace welded wire mesh?
Yes. TW50 provides sufficient tensile and flexural strength to replace welded wire mesh in many slab and pavement applications. Consult your structural engineer for project-specific confirmation.

What is the recommended dosage?
Dosage varies by application and design requirements. Contact us for dosage guidance specific to your project.

Does the PE bag need to be opened?
Yes. Unlike water-soluble or pulpable bags, the PE bag should be opened and the fiber added directly to the mixer.

Is TW50 compatible with admixtures?
Yes. Polypropylene fiber is chemically inert and compatible with standard concrete admixtures.

Do you offer volume pricing?
Yes — contact us for case and pallet pricing.
