Basalt fiber composite bar is a new material formed by pultrusion and winding of high-strength basalt fiber and vinyl resin (epoxy resin).
Advantages of basalt fiber composite bars
1. The specific gravity is light, about 1/4 of that of ordinary steel bars;
2. High tensile strength, about 3-4 times that of ordinary steel bars;
3. Acid and alkali resistance, insulation and magnetic insulation, good wave transmission performance and good weather resistance;
4. The thermal expansion coefficient is similar to that of concrete, which significantly reduces early cracks;
5. Convenient transportation, good designability and high construction efficiency;
6. Improve service life and reduce maintenance costs;
7. The loss of steel bars is reduced by 6%.
Application field
1. Application of concrete bridge structure
In the cold winter, a large amount of industrial nitrate is sprinkled on bridges and roads every year to prevent freezing. However, the corrosion of salt water to traditional reinforced concrete bridges is very serious. If the composite reinforcement is used, the corrosion problem of the bridge can be greatly reduced, the maintenance cost can be reduced, and the service life of the bridge can be increased.
2. Application in road construction
In road construction, the concrete pavement and prestressed concrete highway mainly adopt frontier reinforcement need to improve the durability. Because the use of road salt in winter will aggravate the corrosion of steel bars. In order to solve the problem of anti-corrosion, the use of composite reinforcement in the road shows great advantages.
3. Application in structural concrete fields such as seaports, wharfs, coastal areas, parking lots, etc.
Whether it is a high-rise parking lot, a ground parking lot or an underground parking lot, there is a problem of anti-freezing in winter. The steel bars of many buildings in coastal areas are significantly deteriorated due to the corrosion of sea salt in the sea breeze. The tensile strength and elastic modulus of black fiber composite bars are superior to those of steel bars, making them the best choice for reinforcement of underground engineering. At the same time, they are also widely used in tunnel concrete reinforcement and underground oil storage facilities.
4. Application in anti-corrosion buildings.
Domestic and industrial wastewater is a major source of corrosion of steel bars, and other gaseous, solid and liquid chemicals can also cause corrosion of steel bars. The corrosion resistance of composite bars is better than that of steel bars, so it can be widely used in sewage treatment plants, wastewater treatment equipment, Shishan chemical equipment, etc.
5. Application in underground engineering.
In underground engineering, composite reinforced grating is usually used for reinforcement.
6. It is used in components in the field of low conductivity and non-magnetic fields.
Due to the electrical insulation and easy penetration of electromagnetic waves of composite bars, concrete buildings are used in the field of preventing personal hazards due to current induction or short circuit and protecting sensitive electronic communication equipment, making full use of the non-magnetic and non-conductive properties of composite bars. It is widely used in the foundation of magnetic resonance imaging facilities in medical construction departments, airports, military facilities, communication buildings, anti-radar interference buildings, high-level office buildings, earthquake prediction observation stations, electronic equipment rooms, etc. The use of basalt composite bars can also prevent the occurrence of electric shock accidents in buildings due to current induction or leakage.
