The difference in cementation type has certain impact on the difference between the two strengths, but …
Fossiliferous limestone is a type of sedimentary rock that contains abundant fossils. It is formed through the accumulation and compression of organic remains, such as shells, coral, and other marine organisms, along with sediments. The fossils preserved in fossiliferous limestone provide valuable insights into past life forms …
Limestone mainly consists of hard brittle minerals, such as quartz, ankerite, calcite, pyrite, with area percentages of 65.91–59.56%, 21.50–9.22% and 2.34–1.36% respectively. Water-sensitive minerals could be identified in the specimens, such as illite and chlorite, with an average area percentage of 2.32% and 1.57%, respectively.

According to the analysis of brittle fracture characteristics of rock by Martin and Chandler [24], the mechanical characteristics curve of limestone can be roughly divided into five stages (taking Fig. 11 a as an example): Initially, under the action of axial load, the original fractures of limestone are gradually compressed and closed (stage I ...
The degree of water-rock interaction affecting the accurate identification of mine water inrush source. • The cation exchange controls the formation of low Ca 2+ (Mg 2+), and high Na + (K +) mine water.. Eliminating the influence of cation exchange, Ordovician limestone, 14 th limestone, and water inrush samples have the same …
Particle breakage is one of the issues that significantly affect the strength characteristics of aggregate. In this paper, the strength of pre-crushed limestone aggregate was evaluated through investigating the friction angle, stress–strain behaviour, and single-particle strength. The particle breakage phenomenon was studied for samples prepared …

Brittle creep of the limestone is associated with dilatancy and the development of a shear fault at final strains lower than 2%, as previously observed for other brittle materials. Semibrittle creep leads to inelastic compaction accommodated by crystal plasticity and then to dilatancy likely due to the nucleation and propagation of cracks at ...
