6mm Length 13 Micron Filament Diameter Silane Sizing Chopped Basalt Fiber Strands for Cement Concrete Reinforcement Improving Crack Resistance and Alkali Resistance

6mm Length 13 Micron Filament Diameter Silane Sizing Chopped Basalt Fiber Strands for Cement Concrete Reinforcement Improving Crack Resistance and Alkali Resistance

This product consists of chopped basalt fiber strands with an average filament diameter of 13 μm and a cut length of 6 mm, surface-treated with a silane-based sizing system. It is specifically engineered for dispersion reinforcement in cement concrete, mortar, and shotcrete, where the primary objectives are crack suppression and durability enhancement in alkaline cementitious environments. The 6 mm length is matched to the scale of fine aggregate and cement matrix heterogeneity, promoting uniform filament distribution without balling or agglomeration during mixing. The 13 μm filament diameter sits in the range commonly associated with a favorable balance between filament count per unit mass and individual filament stiffness—thin enough for high reinforcement density, yet robust enough to survive mixing shear forces.
 
General Specifications

 
Increasing performance of friction material:
 
Basalt fiber is an eco-friendly, high-performance reinforcement for friction materials (brake pads, clutches), offering superior wear resistance, thermal stability, and low noise compared to asbestos or steel. Its high-temperature resistance and stable friction coefficient make it an ideal, sustainable alternative for enhancing frictional performance and durability in automotive applications.
 
Key Advantages in Friction Materials:
High Thermal Stability: Basalt fibers maintain structural integrity at high temperatures, reducing thermal fade in braking systems.
Superior Wear Resistance: Studies show basalt fiber-reinforced materials offer better wear resistance than asbestos, steel, and glass fibers.
Improved Frictional Stability: Basalt fiber reduces friction fluctuations, providing consistent performance.
Environmental Friendly: As a natural volcanic rock product, it provides a green, non-toxic, and non-corrosive alternative to traditional fiber reinforcement.
Enhanced Mechanical Strength: It increases the tensile strength and modulus of organic brake pads.
 
Applications and Performance:
Brake Pads: Used to improve friction stability and reduce noise.
Clutch Facings: Provides durability under high-stress conditions.
Optimal Properties: Research indicates that using 10 mm length fiber at appropriate content levels yields the best reinforcement for friction composites.
 
Basalt fiber's ability to withstand high temperatures (up to 900 ℃ in some cases) without losing strength ensures it is highly effective in demanding braking environments.
 
 
Concrete improvement
 
Compared with different types of reinforcing fibers, Pasia Basalt fibers have achieved the best overall technical and economic benefits in fiber-reinforced concrete and maintain a leading position among natural mineral fibers. They are made from short-cut basalt fibers produced by our company. Tests conducted by international research centers and the application effects of the products in actual projects have both confirmed this.
 
Basalt chopped strands are essential products for:
Eliminate large concrete surface cracks;
Make reinforced concrete structures achieve stability and toughness when bearing different loads;
Reduce the backflow during shotcrete application;
Improve the wear resistance of the concrete surface;
Enhance the frost resistance and waterproof performance;
And accelerate the drying process of large concrete blocks.
