Properties of Stones and Tests Applied on Stones
The more compact grained and heavier a stone the harder it is. Due to alternate wetting and drying the resulting crushing strength can be reduced even up to 30-40%. Being dry stones allow more crushing strength than when wet. It is the ability of a stone to endure and maintain its essential and distinctive characteristics i.e. resistance to decay, strength and

Basalt vs Granite: What are the differences?
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 is formed when hot lava cooled quickly on the surface of the earth.

Non-linear shear strength for rock, rock joints, rockfill and
Although intact rock is frequently represented by linear Mohr–Coulomb shear strength envelopes, the actual true behaviour, if taken over a wide range of confining stress, is extremely non-linear. Why is this important? Probably because the real stress across points of contact in both rockfill and rock joints is approaching (or trying to exceed) the crushing …

Railway ballast material selection and evaluation: A review
The different rock types influence the track serviceability. For example, in [40], the effect of rock strength on ballast degradation and settlement was studied. The rock strength was evaluated by the uniaxial compression test on intact rock core specimens. High compression values of the intact rock core reduced the settlement rate of ballast.
