Fundamental research on single-particle breaking and the uniaxial compressive strength (UCS) of carbonaceous mudstone aggregates at different water contents was carried out to investigate the relationship between the single-particle crushing strength and UCS. Based on elasticity theory and the superposition principle, a shape …
Estimating compressive strength. General rock failure criterion can be reduced to a few parameters dependent on lithology (m) and the uniaxial compressive strength (C 0).Lithology is commonly derived during log analysis, so m may be estimated (Table 1).What is needed still is an initial measure of rock strength provided by C 0. C 0 …

Results of the unconfined compressive strength tests on basalt y indicated, that as the loading rate was increased from 1 to 1.60 x 10 psi/sec, ultimate strength, total axial …
Aggregate crushing resistance of three aggregates was intentionally very different - crushing resistance of basalt aggregate was the highest (96 %) and that of …
Basalt 1 had a tuff content of less than 5%, while basalt 2 had a tuff content of about 15%. Volcanic tuffs are characterized by lower fragmentation and wear …
Particle geometry is a result of natural processes, such as the genesis of parent rock, particle transportation and depositional history. For granular materials, the particle morphology has a significant effect on its crushing strength in geotechnical engineering. The particle morphological parameters, sphericity, aspect ratio and …
The analysis showed that for grits of the 10–14 mm fraction, the lower values of the LA indices were obtained, which allows for obtaining a bigger index of crushing strength than in the case of ...
BF is a multifunctional fiber with acid and alkali resistance, low- and high-temperature resistance (it can be used at −260 to 700 °C, while glass fiber is only −50 to 300 °C), good wettability, and other excellent qualities [18].Because BF has a three-dimensional molecular structure, it can improve the compressive and shear bond …
Wu et al. [13] conducted a study to determine the strength and durability of aggregates used in asphalt concrete. 16 different aggregate resources, from good to bad, were used in the study. As a result of the study, the place of the conditioned basalt aggregate in the durability index was found low.
Basalt is a dark-colored, fine-grained, highly hard igneous rock. It is made up of plagioclase, pyroxene, and magnetite minerals. Both pyroxene and magnetite in basalt are iron-rich, and this gives the rock its dark color. ... Basalt's high abrasion resistance, compressive strength, and chemical resistance make it an ideal rock for …
