ROCK STRENGTH: THE INTERRELATIONSHIP BETWEEN STRENGTH INDICES FROM CRUSHED ROCK AGGREGATE AND INTACT ROCK. This paper presents the results of a pilot study of various Scottish igneous rocks, which aimed to compare values of aggregate strength from different tests and the relevance of values obtained from intact rocks as indices of aggregate quality.

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.

Crusher Wikipedia. A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.
