1. Chopped basalt fiber Basalt fiber is a kind of inorganic fiber material. Chopped basalt fiber is an inorganic mineral fiber with a length of less than 50mm and can be evenly dispersed in cement concrete. 2. Characteristics of chopped basalt fibers (1) The naturalness of raw materials. Because the raw material for producing continuous basalt fiber depends on the natural volcanic extrusive rock, there are no ingredients harmful to human health except that it is inherently high in chemical stability and thermal stability. (2) Comprehensive performance. Basalt fiber is acid resistant and alkali resistant. It is both low temperature and high temperature resistant. It is insulated and insulated by heat and electricity. Its tensile strength is higher than that of large tow carbon fiber. Its elongation at break is even better than that of small tow carbon fibers. It has high compressive strength, shear strength and adaptability to aging, and has good comprehensive properties in harsh environment. (3) Low cost. The price of basalt fiber used in cement concrete is significantly lower than that of steel fiber and polyester fiber. (4) Natural compatibility. Basalt fiber is a typical silicate fiber, which is easy to disperse when mixed with asphalt concrete, cement concrete and mortar. The newly mixed basalt fiber concrete has stable volume, good workability and durability, and has superior high temperature resistance, anti-seepage, crack resistance and impact resistance.

Produced by Chongqing Hesheng Longgang Technology Co., Ltd. (manufacturer) Basalt fiber reinforcement (new material to replace reinforcement) Product Description: basalt fiber reinforced bar (BFRP) is a new composite material formed by pultrusion process. It is made of basalt fiber as reinforcement, resin, filler and curing agent. Now it has been widely used in construction, highway and bridge constructionã?? Basalt fiber reinforcement can completely replace ordinary steel reinforcement and deformed steel; Compared with ordinary reinforcement, it has strong advantages: (see Annex for technical parameters) 1. The cost is the same as that of ordinary reinforcement; 2. The strength is 200% of the ordinary reinforcement with the same specification and diameter; The tensile strength reaches 1100mpap; The reinforcement is only 450MPa, 3. Basalt fiber reinforcement, especially with high acid, alkali and corrosion resistance, is a kind of electrical insulator that will never rust. 4. Basalt fiber reinforced bar, which is non-magnetic. It has high tolerance to the moisture concentration in cement mortar and the penetration and diffusion of carbon dioxide, and can prevent the corrosion of concrete structure in harsh environment, so as to improve the durability of buildings and bridges. 5. The specific gravity of basalt fiber reinforcement is 2.1g/cm3; The specific gravity of steel and reinforcement is 7.85/cm3; The diameter weight of the same specification is 370% lighter than that of steel reinforcement, and the strength is 200% of that of steel reinforcement. 6. The physical properties of basalt fiber reinforcement are higher than that of steel reinforcement, and the cost is the same as that of steel reinforcement, which is of epoch-making significance to replace steel reinforcementã??
