 — Based on the simulated results of single particle crushing for basalt, the Weibull strength distribution is graphically presented in Fig. 10. It illustrates a linear relationship between and for individual basalt particles, with a determination coefficient of 0.978. The corresponding Weibull modulus is calculated as 2.782, while the ...

 — Research on the dynamic tensile behaviour of microwave-irradiated rock is of great significance to microwave-assisted tunneling and mining. In order to study the effect of microwave heating and rapid cooling on the mechanical properties of basalt, dynamic Brazilian splitting tests were conducted using the split Hopkinson pressure bar (SHPB) …

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.

 — In composite materials, currently the main field of application experienced for basalt fiber, the fiber and the matrix play the role of support and load transfer, respectively; in this reciprocal collaboration, it is essential to verify and possibly improve the characteristics of the interface, i.e., the small surface portion where the matrix and fiber …

metamorphic rocks. In the sedimentary and metamorphic rocks, the presence of planes of weakness along bedding planes, greatly affects the compressive strength, both in direction and magnitude. The sand stone may show a very low crushing strength when loaded parallel to bedding planes than when loaded perpendicular to the same structure.

 — Uniaxial Compressive Strength (σ c)Unconfined compressive strength is the most important index property obtained from the tests conducted on L/D ratio of 2.0 specimens as per the ISRM [] test procedure [6, 17, 50, 112].To achieve the uniform stress distribution and to minimize end friction, the Teflon sheets of 0.5 mm thickness are …

 — The loading speed of the virtual crushing test is set to 0.01 m/s. The influence of microcracks on the Weibull distribution of crushing strength is considered from three aspects: quantity, location and direction. The characteristic strength of Weibull distribution of basalt particles is positively correlated with the number of microcracks.

When the compressive strength is tested by a method providing a lateral support, as by keeping the specimen in a special cell filled with a liquid under pressure. The value obtained, then it is called as confined or triaxial compressive strength. The crushing strength of a rock depends on a number of factors, such as its i. Mode of formation ii.
