crushing strength of the rock

Definition of crushing strength

A crushing strength of 4,000 lb means that a cubic inch of the rock withstands pressure to 4,000 lb (111 kg/cm 3) before crushing. The crushing strength is greater with shorter prisms and less with longer prisms. Ref: Fay ii. The pressure or load at which a material fails in compression; used for comparing the strength of walling and lining ...

Compressive strength of rocks - PetroWiki

2015-6-4  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
