Rock mass strength is scale dependent and varies with the volume of rock under consideration. The modes of failure of intact rock are multiple. Rock can fail in tension, compression or shear. This depends on the load configuration, the geometry of the problem and how the loads are applied and distributed.

### Basalt fiber - Wikipedia

The basalt fibers typically have a filament diameter of between 10 and 20 μm which is far enough above the respiratory limit of 5 μm to make basalt fiber a suitable replacement for asbestos. They also have a high elastic modulus , resulting in high specific strength —three times that of steel .
