Compressive strength of rocks - PetroWiki

Jun 04, 2015  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 can be estimated from porosity or sonic velocities, but

Concrete recycling Heavy Equipment Forums

Nov 11, 2013  So they rate concrete in psi right? Like 2500 psi to like 4000 psi, or something like that. Is that relevant to the breaking strength? The rock I am crushing daily is anywhere from 29k psi to 40k psi compressive strength. If I'm thinking along the right lines, that would make concrete much easier to crush than my material.

Uniaxial Compressive Strength - an overview ...

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 strength σ c and tensile strength σ t ...

The compressive strength of the material would correspond to the stress at the red point shown on the curve. In a compression test, there is a linear region where the material follows Hooke's law.Hence, for this region, =, where, this time, E refers to the Young's Modulus for compression.In this region, the material deforms elastically and returns to its original length when the stress is removed.
