    How strong is basalt rock? The rock specimens were tested at 0.001/s strain rate to determine the uniaxial compressive strength. The tests on each type of rock are repeated three times and the average strength values are presented in Table 1. The static uniaxial compressive strength of compact basalt is found to be 58.58 MPa.
