What are the applications of crushed basalt sand?

Basalt is a relatively hard rock commonly used in manufactured sand production lines. However, due to its physical properties, specific equipment must be selected for processing. So, what are the applications of crushed basalt sand?

1. Railway and airport runway construction: Basalt aggregate boasts low water absorption, chemical stability, and strong asphalt adhesion, making it a premium choice for railway ballast and airport runway surfaces.

2. Architectural and decorative materials: Basalt aggregate serves as an excellent building and decorative material, suitable for outdoor stone applications, landscape construction, and paving stones.

3. Concrete Mixing: Porous basalt aggregate can be blended into concrete to reduce weight while maintaining strength, durability, and providing sound and thermal insulation.

4. Industrial Applications: It is also utilized in industrial filters, catalysts, and other industrial processes.
