Dynamic compressive properties of Kalgoorlie basalt rock ...

Nov 01, 2020  In this study, the basalt rock extracted from the Kalgoorlie region of Western Australia is intensively studied on its compressive properties under both static and dynamic loads covering strain rate between 2.22 × 10-6 /s to 408/s. The ultimate compressive strength and corresponding failure strain are quantified.

Aug 01, 2013  Porosity is a significant physical feature of rocks due to water absorption that causes decrease in the strength. The basalt of the study area can be described as “highly porous” and ignimbrite as “extremely porous” according to the classification by Anon (1979).The average UCS of basalt is determined as 26.65 MPa.For the ignimbrite, the lowest UCS is

Basalt Rock Properties and Uses - Science Struck

Mar 23, 2015  The rock hardness of basalt is 6 on the Mohs scale, and can be seen through a combination of its compressive strength: 100-300 Mpa (Megapascal), its tensile strength: 10-30 Mpa, and its shear strength: 20-60 Mpa, which denotes that depending on the mineral makeup, basalt rocks fall in the strong – very strong category.

Overall, axial compressive strength for Pacaya basalt ranges widely from 12 to 174 MPa (Table 3), with the lower end falling into strength categories as low as chalk . Given that the porosity of the rocks scales with permeability, we chose to assess the relationship of UCS with permeability, as this measures the strong control that cracks have ...

Jun 25, 1993  Rock mass strength is defined by three parameters including unconfined compressive strength of intact basalt and two others related to the degree of fracturing of the material. Experimental results for elevated temperature extend the applicability of these parameters to the near-surface environment of Venus.

Relationships Between Unit Weight, Unconfined Compressive ...

Jun 27, 2010  Qualitatively, the strength of vesicular basalt is inversely proportional to the amount of pore space within the rock; as the macroporosity increases, the UCS decreases. Finding a reliable method to quantitatively estimate the strength of vesicular basalt without extensive laboratory testing would be of great benefit to the engineering community.
