performance new material Basalt fiber rebar
1. fiber rebar

Basalt fiber rebar (BFRP) is a new type of composite material formed by pultrusion with basalt fiber as reinforcement, resin, filler and curing agent. It is a non rusting electrical insulating material. It is non-magnetic, especially with high acid and alkaline resistance. In particular, basalt fiber rebar has the characteristics of high corrosion resistance and light weight, which is of great significance for prolonging the service life of the structure, reducing maintenance costs, saving resources and reducing the weight of the structure in the highly corrosive environment. 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 the harsh environment, So as to improve the durability of buildings. It is also expected to fundamentally solve the corrosion problem of reinforced concrete structures. Now it has been widely used in construction, highway and bridge construction. A large number of engineering examples show that basalt fiber reinforcement can effectively control the generation and development of cracks, prevent water infiltration in the road (bridge) area, prevent the corrosion of reinforcement in the structure, solve the problem that the reinforcement in the bridge (pavement) engineering structure is not corroded or delayed in the corrosive environment, improve the overall service performance of the road (bridge) surface and prolong the service life, which is of great significance.
Classification:Basalt fiber rebar is divided into threaded reinforcement and non threaded reinforcement. The basalt fiber rebar applied in cement concrete shall adopt threaded reinforcement to enhance the grip force between reinforcement and concrete.

Basalt fiber rebar is 200% of the strength of ordinary reinforcement; It will never rust and has a service life of 100 years.

4.1 characteristics
Basalt fiber rebar concrete can significantly prolong the service life of cement concrete structure in corrosive environment. Compared with traditional reinforced concrete structure, basalt fiber reinforced concrete has excellent mechanical, physical and chemical properties.
(1) High strength, tensile strength ≥ 1000 (MPa), more than twice that of ordinary reinforcement;
(2) Excellent corrosion resistance, basalt fiber rebart is an electrical insulator that will never rust. Solve the corrosion resistance and service life of reinforced concrete structures of bridges and pavements in areas with harsh acid-base environment (incomparable with any other material);
(3) The density is small. The density of basalt fiber rebar is 1.9 ~ 2.1 g / cm³, which is only about 1 / 4 of that of ordinary reinforcement;
(4) The thermal expansion coefficient of basalt fiber rebar is similar to that of concrete, and there will be no large temperature stress between them;
(5) Non magnetic, electrical insulation, good wave transmission performance, no shielding;
(6) Non conductive and non-conductive.
(7) The physical properties of basalt fiber rebar are higher than that of steel reinforcement, and the use cost is lower than that of steel reinforcement, which is of epoch-making significance to replace steel reinforcement.

Basalt fiber
The development of basalt fiber began in the Soviet Union in the 1960s. At that time, basalt fiber exceeded glass fiber in some characteristics, its strength was higher than steel, and its high strength retention rate at high temperature of 700 º C attracted the attention of the Soviet . After more than 20 years of continuous practice, Soviet scientists finally developed the production process and technology of basalt continuous fiber.
Continuous basalt fiber (CBF) is a new type of inorganic fiber material with high performance. It is a continuous fiber made of volcanic rock (a variety of basalt, natural basalt stone mainly composed of oxides such as silica, alumina, calcium oxide, iron oxide and titanium dioxide) as raw materials, melted at 1450 ºC ~ 1500 ºC and pulled at high speed through platinum rhodium alloy wire drawing leakage plate. Because the fiber color is golden brown, it is also known as "golden fiber". Continuous basalt fiber has the advantages of good stability, good electrical insulation, corrosion resistance, flame retardant, high temperature resistance and low temperature resistance. It has excellent comprehensive performance, low raw material cost, natural environmental protection and high cost performance. Basalt fiber is a pure natural inorganic non-metallic material, which can be degraded into soil parent material and absorbed by soil. It is a green environmental protection product.

Performance characteristics of basalt fiber:
1. Outstanding temperature resistance. The service temperature range of CBF is: - 260 ~ 900 ºC (softening point is 960 ºC).
2. Outstanding tensile strength: the tensile strength of CBF is 3800 ~ 4800 MPa.
3. Natural compatibility with silicate. It belongs to silicate like cement and has stable performance in alkaline medium.
4. Outstanding chemical stability, excellent acid and alkali corrosion resistance and water resistance.
5. Significant thermal vibration stability. The mass loss fraction of CBF at 900 ºC is only 0.03.
6. Good dielectric properties. The volume resistivity is one order of magnitude higher than that of glass fiber, and the dielectric loss tangent is 50% lower than that of glass fiber.
7. Excellent wave transmission performance and certain wave absorption performance.
8. It has good radiation protection function.
9. Flame retardancy: in case of open fire, it will not burn.
