Boxes that pass this standard are ...

Compressive strength of rocks

 · 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 …

What is the difference b/w compressive strength and ...

Compressive strength is the load (measured in pounds/sq. in. or /sq.ft.) which the concrete (poured over a solid base) will support, without damage. Specifically, by being crushed. If the load gets large enough, the concrete will fracture and be c...
