## Description

This alkali-resistant chopped fiberglass is designed for mixing into concrete, cement, and mortar applications to enhance material performance. The glass fibers disperse throughout the mix, helping to control plastic shrinkage and reduce the formation of micro-cracks as the material cures. This contributes to improved impact resistance and overall durability of the finished product. The fibers are made from AR-glass, formulated to withstand the alkaline environment present in cementitious mixtures, ensuring long-term stability. This reinforcement is suitable for a variety of projects including countertops, patio elements, decorative pieces, pools, and exterior wall finishes. It aids in increasing the density of the mix, which can help mitigate permeability issues. When added according to guidelines, it integrates smoothly to improve the toughness and cohesiveness of the material without compromising workability. It is a common choice for reinforcement in glass fiber reinforced concrete (GRC) and other composite products seeking added tensile strength and crack control.

• Crushed fiberglass for concrete and mortar reinforcement
• Alkali-resistant fibers to withstand high alkaline conditions
• Increased density of mix reduces water penetration
