New rebar material (basalt fiber rebar)

Product Description

 

Basalt Fiber Reinforced Bar

 

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 construction。

Our company adopts new technology and new process. Under the condition that the physical properties of the products remain unchanged, the purchase cost of basalt fiber rebar reaches the level of ordinary steel rebar.

 

Basalt fiber reinforcement rebar 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 of ordinary reinforcement is lower than 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 rebar, 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 reinforcement.

FAQ

Is basalt fiber expensive?
Basalt fiber is more expensive than E glass fiber, but much less expensive than carbon fiber.

How is basalt fiber made?
Basalt fibers are pultruded from volcanic rock and melted in a blast furnace. In contrast to extrusion, fibers are drawn. The process produces a continuous fiber reinforced with a polymer.

Is basalt stronger than concrete?
Adding fibers can improve the brittleness of plain concrete. Compared with plain concrete, basalt fiber concrete has the advantages of strengthening, toughening and crack resistance. Compared with steel fiber reinforced concrete, basalt fiber reinforced concrete has better construction performance.
