Stone Crushing
The crushing-strength test is not practiced as a rule except on stone intended for building purposes. The fact is that most rocks have adequate compressive resistance for structural purposes. Crushed stone does not lend itself to the compression test very readily unless the sample is taken from the ledge rock before it is crushed.
