3.2LB Fibersglass for Concrete, 3/4 Inch Chopped Strand Fiberglass Reinforcement for Cement, Alkali Resistant Concrete Fibers for Crack Prevention, Countertops, Pools & Decorative Projects

Strengthen Your Concrete Projects with Professional-Grade AR Glass Fibers Upgrade your concrete, mortar, and GFRC projects with high-performance alkali-resistant fiberglass reinforcement. These 3/4-inch chopped strands are specifically engineered to increase tensile strength, reduce cracking, and improve impact resistance without adding unnecessary weight. Designed for both professionals and DIY enthusiasts, the fibers disperse evenly throughout the mix, creating a stronger and more durable structure that stands up to demanding environments.

• ✅ PROFESSIONAL AR GLASS FIBER REINFORCEMENT:Made from premium alkali-resistant (AR) glass fibers, these chopped strands significantly improve the tensile strength, impact resistance, and overall durability of concrete, mortar, and cement-based materials.
• ✅ REDUCES CRACKING & SHRINKAGE:Distributes evenly throughout the mix to minimize shrinkage cracks, improve structural integrity, and enhance long-term performance. Ideal for preventing surface fractures and extending the lifespan of concrete projects.
• ✅ DESIGNED FOR GFRC & CEMENT APPLICATIONS:Perfect for GFRC (Glass Fiber Reinforced Concrete), cement mortar, calcium silicate products, gypsum products, countertops, planters, patio steps, swimming pools, decorative panels, and architectural projects.
• ✅ EXCELLENT ALKALI, MOISTURE & CORROSION RESISTANCE:Unlike ordinary fibers, AR glass fibers are engineered to withstand highly alkaline cement environments without degrading, delivering reliable reinforcement in both indoor and outdoor applications.
• ✅ EASY TO MIX & LARGE 3.2LB SUPPLY:Each package contains 3.2 lbs of 3/4-inch chopped fiberglass strands that disperse easily into concrete mixes without clumping. Suitable for contractors, builders, and DIY users tackling small to large projects.
