Alkali-resistant chopped fibers for plastic shrinkage crack control

Highly dispersible alkali-resistant chopped glass fiber is an engineering-grade reinforcement fiber specially designed for concrete and cement mortar.
At low dosage, it can effectively control plastic shrinkage cracking and greatly improve the durability and mechanical performance of the substrate.

**Main Advantages**
✅ Excellent dispersibility: The 12mm fiber can disperse to about 200 million individual filaments per kg, easy to mix evenly with mixtures.
✅ Efficient anti-crack: Forms a uniform 3D reinforcement network during the plastic stage of concrete, restraining the propagation of microcracks.
✅ Good surface finish: Fibers do not protrude from product surface. No extra troweling or surface treatment required, keeps decorative surface smooth.
✅ Safe & durable: Alkali corrosion resistant, non-corrosive, non-dangerous goods, simple & safe operation.
✅ Low dosage high efficiency: Good reinforcing effect at recommended low addition rate.

**Application Range**

- All kinds of concrete projects (site mixing or ready-mix concrete)
- Industrial & commercial floor screeds
- Mortar base leveling and special mortars
- Can be directly added into central mixing plant or ready-mix concrete truck (suggest adding after aggregate mixing)

Product Description

Alkali-resistant Chopped Glass Fibers for Plastic Shrinkage Crack Control

Product Introduction

This alkali-resistant chopped glass fiber is engineered for cementitious systems including concrete and cement mortar. With excellent dispersion performance, it can distribute uniformly inside the mortar matrix. It restrains plastic shrinkage cracks at early age and enhances the overall toughness and durability of hardened concrete.
