ELT-Twist is actually a Hybrid of two fibers:A standard fibrillated polypropylene fiber to reduce and control shrinkage and temperature cracking. A twisted-bundle monofilament fiber made of a strong synthetic copolymer, to increase load-transfer and post-crack performance. ELT-TWIST fibers comply with ASTM C1116, Standard Specification for Fiber Reinforced Concrete and Shotcrete, and are specifically used for the reduction of plastic shrinkage cracks, to improve impact, shatter and abrasion resistance, to increase fatigue resistance, to increase toughness of concrete and provide long term durability of concrete, structural enhancements and cement based building products.

Functions:

1. Increases impact, shatter and abrasion resistance of concrete
2. Reduces segregation, plastic settlement, and shrinkage cracking of concrete 
3. Provides three-dimensional reinforcement against macro-cracking 
4. Increases overall durability, fatigue resistance and flexural toughness 
5. Reduction of in-place cost versus wire mesh for temperature / shrinkage crack control 
6. Easily added to concrete mixture at any time prior to placement

Dosage rates will vary depending upon the reinforcing requirements and can range from 2kg/m3 to 5 kg/m3
