Basalt is a hard black extrusive igneous rock. Extrusive means it comes mainly from volcanic eruptions. It has a low silica content which enables this lava to flow quickly and allows volcanic gases to escape without explosive events. It is a fine grained rock and is the most common rock type in the Earth s crust.

Basalt fiber is a relative newcomer to fiber reinforced polymers (FRPs) and structural composites. It has a similar chemical composition as glass fiber but has better strength characteristics and unlike most glass fibers is highly resistant to alkaline acidic and salt attack making it a good candidate for concrete bridge and shoreline structures.

2006-3-19 · In general rock mass strength depends on the strength of intact rock and the strength of rockdiscontinuities. In general compared to intact rock a rock mass has reduced tensile strength(almost zero) and reduced shear strength especially along discontinuity planes. Furthermore if a rock mass is cut by directional joint sets the rock mass strength is anisotropic. Rock massstrength is scale dependent
