Crushability and compressibility of carbonate and siliceous

The compression of sedimentary strata is a function of effective stress and grain framework. Reduction of primary void ratio begins with grain-scale frictional slip, rotation, and sliding. Crushing would be the most prominent cause of compaction at high-level stresses and enhanced deformation as noted by Chuhan et al. ( 2003 ).

Uniaxial Compressive Strength

The uniaxial compressive strength of a rock under static loading often decreases with an increasing temperature at which the rock has been heat-treated before strength testing. This conclusion is drawn from a great number of experiments [1,2,4,8,9,11,17–19].The higher the temperature is, the lower the strength. Some results for uniaxial compressive …

(Soil cannot usually be at a state outside the normal compression line unless it is bonded or structured). At a state A the overconsolidation ratio is R p = p' y / p' a (on NCL R p = 1.0 and soil is normally consolidated). Note: p' y is the point of intersection of the swelling line through A and the NCL. This is usually close to the maximum ...

Rock Strength

The tensile strength of rock is defined as the pulling force, required to rupture a rock sample, divided by the sample's cross-sectional area. The tensile strength of rock is very small and is of the order of 0.1 times the compressive strength. Thus, a rock material is more likely to fail in tension than in compression.
