Product type
Basalt aggregates are crushed stone materials derived from volcanic rock, known for their strength and durability. These aggregates are produced by crushing basalt rock into various sizes, making them suitable for a range of construction applications. They are commonly used in concrete production, road construction, and as base materials for various types of infrastructure projects.
| Material | Basalt rock |
| Size range | From fine aggregates to larger stones (typically 0.5 to 2 inches) |
| Density | Approximately 2.8 to 3.0 g/cm³ |
| Absorption rate | Typically 1-3% |
| Crushing strength | High compressive strength, often exceeding 200 MPa |
When selecting basalt aggregates, consider the intended application and required size specifications. It's important to specify the desired size range, as well as any specific performance characteristics such as density and absorption rates. Additionally, inquire about the source of the aggregates to ensure they meet local regulations and standards.
