Basalt fiber composite ribs are currently widely used in basalt fiber composite materials. Although there is currently competition for glass fiber composite ribs and carbon fiber composite ribs, basalt fiber composite ribs still have a place in the field of architectural applications due to their unique performance characteristics. Therefore, the editor still feels it is necessary to introduce the characteristics of basalt fiber composite ribs to you.
Basalt Fiber Reinforced Plastics (BFRP for short) is a new non-metal composite material formed by basalt fibers as reinforced materials and synthetic resin as matrix materials, and pultrusion technology and special surface treatment. Basalt fiber composite ribs have excellent physical and chemical properties such as high strength, light weight, corrosion resistance. At the same time, the thermal expansion coefficient of the basalt fiber composite rib is similar to that of concrete, ensuring the synchronous deformation of concrete and reinforced material; in addition, since the material can be continuously produced in the longitudinal direction, the cement concrete used for continuous reinforcement can be configured according to the length of the road section, reducing the longitudinal welding process of reinforced reinforcement, greatly improving the progress of engineering construction, and having a wide range of engineering application prospects.

Core features

‌Physical properties‌: 1 density is 1.9-2.1g/cm³, which is only 1/4 of the steel bar, greatly reducing the structural self-weight.
2 The thermal expansion coefficient is similar to that of concrete, ensuring coordinated deformation with concrete and reducing temperature stress cracks.
‌Mechanical properties‌: 1 Tensile strength is more than 3 times that of ordinary steel bars, and the elastic modulus is matched with concrete.
2Derminant continuous production characteristics simplify the construction process and are suitable for continuous reinforced concrete structures.
‌Chemical stability‌: 1 Excellent acid and alkali corrosion resistance, suitable for harsh environments such as moisture and salt spray, significantly extending the structural life.
2 Non-conductive and non-magnetic, suitable for electromagnetically sensitive scenarios (such as medical facilities, communication base stations)

Advantages

1. The specific gravity is light, about 1/4 of ordinary steel bars;

6. Improve service life and reduce maintenance costs;
7. The loss of steel bars is reduced by 6%.

Table parameters

The basalt fiber composite ribs are subject to the Part 4 of the transportation industry standard of the People's Republic of China "JT/T 776-2010 Highway Engineering Basalt Fiber and its Products": Basalt fiber composite ribs were released on March 25, 2010 and officially implemented on July 1, 2010.

Application Description:

1. Application on concrete bridge structure
In the cold winter, a large amount of industrial nitrates must be spread on bridges and pavements every year to prevent freezing. However, the corrosion of salt water on traditional reinforced concrete bridges is very serious. If composite ribs are used, the corrosion problem of bridges can be greatly reduced, maintenance costs can be reduced, and bridge service life can be increased.
2. Application in road construction
In road construction, concrete pavement mainly uses border reinforcement and prestressed concrete roads need to improve durability. Because the use of salt spread on the road in winter will aggravate the corrosion of steel bars. In order to solve the corrosion prevention problem, the use of composite ribs on the road shows great advantages.

3. Application in structural concrete fields such as harbors, docks, coastal areas, and parking lots.
Whether it is high-rise parking lots, ground parking lots or underground parking lots, there are winter anti-freeze problems. The steel bars of many buildings in coastal areas have significantly deteriorated due to the corrosion of sea salt in the sea breeze. The tensile strength and elastic modulus of the black fiber composite ribs are better than steel bars, making it the best choice for reinforcement and reinforcement of underground engineering. At the same time, tunnel concrete reinforcement and underground oil reserve facilities are also widely used.
4. Application in anticorrosion buildings.
Domestic wastewater and industrial wastewater are major corrosion sources of steel bars, and other gaseous, solid and liquid chemicals can also cause corrosion of steel bars. Composite ribs are more corrosion-resistant than steel bars, so they can be widely used in sewage treatment plants, wastewater treatment equipment, Shishan chemical equipment, etc.

5. Application in underground engineering.
In underground engineering, composite rib gratings are usually used to enhance.
6. Application in components in low conductivity and non-magnetic fields.
Due to the electrical insulation and easy electromagnetic wave characteristics of composite ribs, concrete buildings are used in the field of preventing personal harm caused by current induction or short circuits and protecting sensitive electronic communication equipment. The non-magnetic and non-conductive properties of composite ribs are fully utilized. They are widely used in the basics of magnetic resonance imaging facilities of medical insurance departments, airports, military facilities, communication buildings, radar-proof buildings, high-end office buildings, earthquake prediction observation stations, electronic equipment rooms, etc. The use of Xuanwu composite tendons can also prevent electric shock accidents in buildings due to current sensing or leakage.
