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.

Basalt Rock Formation, Properties, Composition, Uses

Basalt is an igneous rock that contains more than 45 and less than 52% of SiO2 and less than five percent of total alkalies (K2O + Na2O)3. Types of Basalt Basalt types: tholeiites vs alkali basalts Tholeiitic basalt is relatively rich in silica and poor in sodium.

The compressive strength is then defined as the maximum load applied to crush the specimen divided by the cross-sectional area. Rock strength has been found to be size dependent because of the cracks and fissures that are often present in the material. This is illustrated from the results of tests on three rock types in Fig. 8.2.
