Ultrafine Reinforcing Glass Fiber Micro Powder | PIONEER®
Enhance Concrete Durability and Strength with Glass Fiber Powder
Improve your concrete and mortar performance with PIONEER® glass fiber micro powder engineered for crack resistance, toughness, and superior microstructure refinement.
What Is PIONEER® Glass Fiber Micro Powder for Cementitious Reinforcement?
PIONEER® HPM® GFM-50 is an ultrafine reinforcing glass fiber micro powder developed for concrete, mortar, UHPC, and cement-based composites. With particle sizes below 10 μm and high surface area, this alkali-free E-glass fiber powder refines microstructure, enhances toughness, reduces microcracking, and improves long-term durability in advanced concrete systems while maintaining easy dispersion in dry and wet processes.

How Glass Fiber Micro Powder Strengthens Concrete?
Learn how PIONEER® glass fiber micro powder enhances concrete microstructure, increases strength, and improves crack resistance.
The ultrafine particles fill micro-voids, reduce porosity, and refine the interfacial transition zone between aggregates and cement paste. This leads to improved compressive and flexural strength, enhanced bonding, reduced permeability, and increased resistance to cracking, making it ideal for high-performance concrete, UHPC, mortars, and repair materials.
