Dynamic compressive properties of Kalgoorlie basalt rock
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 fibre in concrete is still an exploratory area due to limited studies. Therefore, a systematic study on basalt fibre-reinforced concrete was carried out with percentage volume fraction of fibre 0.50 (13.0 kg/m 3 ), 0.75 (19.5 kg/m 3) and 1.00 (26.0 kg/m 3 ). The increase in compressive, splitting tensile and flexural strength is in theExperimental Investigations on Basalt Fibre-Reinforced Concrete

Enhancing frost resistance and durability of self-compacting
As depicted in Fig. 17, the compressive strength of all concrete mixtures, both with and without basalt fiber (SCCBF0.1%), gradually decreases as the number of freezing–thawing cycles increases. Among all the freezing–thawing cycles, the SCCBF0.3% mixture exhibited the highest compressive strength value of 41 MPa.Casting of concrete specimens.

Prediction of Engineering Properties of Basalt Rock in Jordan
Basalt is an extrusive igneous rock derived from Lava and spread over different localities in Jordan. 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 1) Basalt and Trap: Basalt is an igneous rock, formed by the solidification of molten magma under pressure. Basalt has a medium to fine-grained structure. These stones are basically used as road metals. It has a specific gravity of 1.8-2.9 and a compressive strength of 200-350 N/mm2. Basalt is mostly in dark grey to black in colour.Types of stones used in the construction Basalt, Granite,
