Recommended dosage is 6-8 pounds per cubic yard, balancing durability and workability. Unlike traditional glass fibers, basalt fibers offer superior resistance to acidic, salty, and alkaline environments, making them ideal for decorative and structural applications including GFRC, countertops, and shoreline structures. ## Description Basalt Chopped Fibers can be mixed directly into polymers and concrete to increase tensile strength, reduce cracking and chipping. Perfect for mortar and concrete reinforcement applications; all decorative applications as countertops, fireplace surrounds. Basalt Fiber has a similar chemical composition as regular glass fiber but Basalt Fiber has better strength characteristics, and unlike most glass fibers is highly resistant to acidic and salt attack and alkaline, making it a good option for concrete, bridge and shoreline structures. ## Features - Diameter is 17 microns. - Regular concrete mix dosage: We recommend 6-8 pounds of basalt chopped fibers per cubic yard of concrete. - GFRC concrete mix Fiber content varies but is generally approximately 3% to 7% of the cementitious material weight or 1% to 3% by total concrete weight. Increased fiber content adds strength but decreases workability. Common water to cement ratios used from 0.25 to 0.35. (25-35% by cementitious material weight) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07F446BNV | | Best Sellers Rank | #628,638 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #233 in Concrete | | Brand Name | GlobMarble | | Customer Reviews | 4.6 4.6 out of 5 stars (27) | | Grade Rating | Commercial | | Item Form | Sheet | | Item Shape | Rectangular | | Item Thickness | 17 micrometer | | Item Weight | 0.27 g | | Manufacturer | GlobMarble | | Material | basalt | | Model Number | BCF-24 | | Number of Items | 1 | | Part Number | BCF-24 | ## Product Details - **Brand:** GlobMarble - **Item Form:** Sheet - **Item Thickness:** 17 micrometer - **Material:** basalt - **Shape:** Rectangular ## Images ![Basalt Chopped Fibers for Concrete, GFRC Chopped Strands 1 LB.
