CORRELATION BETWEEN UNCONFINED COMPRESSIVE STRENGTH .
tensile strength is very fast comparing with unconfined compressive strength. Material was created using plaster of Paris and water to simulate as jointed rocks. Three joint conditions were considered for evaluating the unconfined compressive strength using indirect tensile strength (joint orientation, joint roughness and number of joints).

Rock properties
Rocks can be tested for their unconfined fracture strength by using ASTM standard tests. These involve loading a small rock core at a rate of MPa/s until it fails brittlely. The fracture strength is given as the maximum stress necessary to induce failure of the rock core. This value gives an indiion of the cohesiveness and density of a rock.

UNCONFINED COMPRESSION TEST
unconfined compression test led to a significant underestimation of the strength of the soil. In fact, because the unconfined compression test does not provide confinement for the soil, and because of the effects of sampling disturbance, strengths measured in the unconfined compression test are usually a lower bound of the actual strength.
