It can be used in industrial applications, and as construction materials. Before using basalt, it is essential to determine its dry density, porosity, uniaxial compressive strength, and Brazilian tensile strength. The testing procedure and sample preparation used to determine the engineering.

compressive strength of basalt rock

The bearing capacity of a homogeneous, and discontinuous rock mass cannot be less than the unconfined compressive strength of the rock mass around the footing and this can be taken as a lower bound for a rock mass with constant angle of internal friction 0 and unconfined compressive strength qur. Goodman () suggests the following equation ... · The results show that the flexural strength and compressive strength of specimens with basalt fiber is higher compared with normal concrete. Also, by the addition of 2% of fiber, the 14 days flexural strength increased about 40% to 50%- and 28-days compressive strength …basalt rock compressive strength MC Machinery.
