Resistant to extreme temperatures (-452°F to 1,200°F), alkali, acid, and salt attacks, these fibers improve crack resistance and impact durability by up to 260%, making them ideal for high-performance concrete applications like countertops, bridges, 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. Compared to carbon and aramid fiber, Basalt Fiber has the features of wider application temperature range -452° F to 1,200° F (-269° C to +650° C), higher compression strength and higher shear strength, radiation resistance and higher oxidation resistance Diameter is 17 microns Fiber lengths are available in 12 mm, 18 mm and 24 mm / .47", .70", .94" Various sizings are available for compatibility with a wide range of resins, concrete, and water-based adhesives Fibers are completely resistant to the effects of the alkali in concrete, and require no special coatings for concrete use Fibers resist cold down to -260 degrees F, and heat up to 1,500 degrees F Fibers do not conduct electricity or induce electrical fields Fibers do not absorb or wick water into reinforced structures Fibers significantly improves the shock resistance of concrete Ductility index of basalt fiber reinforced concrete increases by a factor of 2~4. The addition of basalt fiber can effectively increase the compressive strength, splitting the tensile and flexural strength (especially splitting tensile and flexural strength) of the concrete; values of 9.9%, 37.5% and 44.2% are attained Crack impact cycle number of the concrete improves by 60%~ 170%, the impact energy improves by 90%~ 260%. ## 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 | B07F41CVFD | | Best Sellers Rank | #580,674 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #203 in Concrete | | Brand | GlobMarble | | Brand Name | GlobMarble | | Color | brown | | Customer Reviews | 4.6 out of 5 stars 28 Reviews | | Grade Rating | Commercial | | Item Diameter | 17 Micron | | Item Form | Sheet | | Item Shape | Rectangular | | Item Weight | 1 Pounds | | Manufacturer | GlobMarble | | Material | basalt | | Model Number | BCF-12 | | Number of Items | 1 | | Part Number | BCF-12 | | Shape | Rectangular | | Specification Met | True | | Unit Count | 16.0 Ounce | ## Product Details - **Brand:** GlobMarble - **Color:** brown - **Item Diameter:** 17 Micron - **Material:** basalt - **Shape:** Rectangular ## Images ![Basalt Chopped Fibers for Concrete, GFRC Chopped Strands 1 LB.
