Dynamic compressive properties of Kalgoorlie basalt rock

Nov 01, 2020· For basalt rocks, Malik et al. 12 investigated Deccan basalt rock and found the dynamic compressive strength between about 170 MPa and 260 MPa at a strain rate of about 400/s to 1600/s. Lindholm et al. 13 found a much lower dynamic strength of about 110 MPa to 125 MPa at a strain rate of about 600/s and 1100/s for Dresser basalt rock.
