Modern construction technologies are rapidly evolving, offering stronger, more durable, and environmentally safe materials. One such material is basalt fiber, which is actively used in the production of composite rebar and mesh. Unlike traditional steel reinforcement, composite materials offer high corrosion resistance, lightweight properties, and superior mechanical characteristics. In this article, we will explore how basalt fiber enhances composite rebar properties, present scientific studies confirming its effectiveness, and discuss the production technologies implemented in Composite-Tech equipment.
What is Basalt Fiber and Why is it Important?
Basalt fiber is produced from natural basalt by melting it at temperatures of 1400–1600°C and then forming continuous fibers. Compared to fiberglass, basalt fiber has higher thermal resistance and durability in aggressive environments. According to studies conducted by the University of Minnesota, basalt fiber exhibits 20-30% higher tensile strength than fiberglass.
Key advantages of basalt fiber:
- High mechanical strength – up to 4840 MPa, which is several times higher than steel.
- Chemical resistance – it does not corrode, making it ideal for use in aggressive environments (seawater, acids, alkalis).
- Low thermal conductivity – 10 times lower than steel, reducing heat loss in buildings.
- Environmental safety – basalt fiber production requires less energy compared to fiberglass, and the raw material is natural and non-toxic.
Composite Rebar and Mesh Based on Basalt Fiber: Stronger, Lighter, More Durable
Composite rebar and mesh made from basalt fiber are used in various construction sectors, from road construction to high-rise buildings. According to research published in the “Journal of Composite Materials,” basalt composite rebar increases the lifespan of concrete structures by 3–5 times compared to traditional steel rebar.
Advantages of using basalt composite rebar:
- Weight reduction of structures – basalt fiber rebar is 4 times lighter than steel.
- Lower transportation and installation costs – composite materials can be transported without heavy machinery.
- Increased resistance to climatic conditions – it is not affected by low temperatures and sudden fluctuations.
Production Technologies: Composite-Tech Equipment
Composite-Tech has developed unique machines that allow the production of composite rebar and malla using both fiberglass and basalt fiber. This provides customers with flexibility in choosing raw materials based on project requirements and material availability.
Features of Composite-Tech equipment:
- Flexibility in using different fiber types – capability to work with both basalt and fiberglass.
- High productivity – machines can produce up to 1000 meters of rebar per shift.
- Energy efficiency – optimized energy consumption reduces production costs.
- Ease of maintenance – automated control systems ensure user-friendly operation.
Successful Application Examples
In recent years, basalt composite rebar has been actively used in infrastructure projects. For example:
- China: The construction of bridges using basalt rebar has extended the lifespan of structures to 100 years without the need for repairs.
- EE.UU: In Florida, basalt composite rebar is used for road reinforcement, reducing maintenance costs by 30%.
- Europe: In Germany, railway platforms are reinforced with basalt mesh, reducing wear and extending service life.
Conclusion
Basalt fiber is the material of the future, already transforming the construction industry. Composite rebar and mesh based on basalt fiber offer exceptional strength, resistance, and durability. Composite-Tech equipment enables the production of high-quality composite products using both fiberglass and basalt fiber, ensuring flexibility and cost-effectiveness in manufacturing.
