High-strength corrosion-resistant basalt rebar
Product Application:
Basalt Fiber Reinforcement Composite (BFRP) is non-magnetic, electrically insulating, with high strength, high modulus of elasticity, and coefficient of thermal expansion similar to that of cement concrete. Extremely resistant to chemical corrosion, acid, alkali, and salt, it can be used in magnetic resonance imaging infrastructures, airports, military facilities, communication buildings, radar interference-resistant buildings, high-end office buildings, seismic prediction observatories, medical insurance and electronic equipment rooms in the construction sector. It has a broad application prospect and great market potential. Such as:
1. Seismic observatories, harbor and dock protection works and buildings, subway stations, bridges, non-magnetic or electromagnetic concrete buildings.
2. Prestressed concrete highway, anti-corrosion chemical, floor slabs, chemical storage tanks, engineering.
3. Magnetic resonance imaging infrastructure, communication buildings, electronic equipment workshops.
4. Concrete slabs for nuclear fusion buildings and maglev railroads.
5. Telecommunication transmission towers, TV station stands, fiber optic cable reinforcement cores.

Product Advantages:
(1) Lightweight, high strength, non-magnetic transmission:
Basalt fiber composite reinforcing bar has the characteristics of lightweight (about 1/4 of ordinary steel bar), high strength (about 4 times of ordinary steel bar), and non-magnetic transmission, and will not affect the normal detection of the protective layer of steel reinforcement;
(2) Excellent acid, alkali, and salt corrosion resistance:
It can effectively solve the problem of steel corrosion in saline and alkaline corrosive environments, and improve structural durability; and
(3) light specific gravity basalt fiber composite tendon easy to use, safe, manual loading and unloading, easy to operate, convenient construction, improve construction efficiency; and no need to use welding and electrical equipment, reducing the process quality and safety risks; at the same time, saving the investment in lifting equipment, effectively reducing the cost of engineering;
(4) High comprehensive benefits:
Comprehensive analysis shows that basalt fiber composite reinforcement in bridge decks, pavements, floor coverings instead of steel bars or steel mesh panels. Material cost and steel reinforcement is basically the same, solve the problem of steel rust expansion, greatly extend the service life of bridge deck and pavement. Using 60% of the effective cross-sectional area instead of ordinary steel reinforcement can save about 30% of the cost. In addition, due to the corrosion resistance of basalt fiber composite reinforcement, its application in marine engineering has more obvious advantages. Ordinary steel reinforcement requires comprehensive corrosion protection measures, such as epoxy coatings, increasing the thickness of the protective concrete layer, applying protective coatings to the concrete surface, and adding rust inhibitors to the concrete. However, basalt fiber composite reinforcing bars are inherently corrosion-resistant and can solve a host of problems in the marine environment at a savings of approximately 40% of the total cost. The key is to significantly improve the durability of the structure.
