The Unconfined Compression Test is a laboratory test used to derive the Unconfirmed Compressive Strength (UCS) of a rock specimen. Unconfirmed Compressive Strength (UCS) stands for the maximum axial compressive stress that a specimen can bear under zero confining stress. Due to the fact that stress is applied along the longitudinal axis, the ... Representative values of strength parameters for intact basalt at ambient temperature (20C) and negligible confining pressure are Youngs modulus, 73 GPa Poissons ratio, 0.25 tensile strength, -14 MPa unconfined compressive strength, 262 MPa fracture toughness, 1-3 MPa m 1/2 cohesion, 66 MPa and coefficient of friction, 0.6.
The difference in the unconfined compressive strength between the slow and the rapid rates of factor for the granite was less than l for the basalt, 1.35 for the limestone, 1.52 and for the tuff, 1.74. The compressional wave velocity of rock is affected by increases in both the applied axial stress and confining pressure. Aug 27, 2015 In order to study the mechanism and effect of basalt fiber reinforced clay soil, a series of unconfined compressive strength tests conducted on clay soil reinforced with basalt fiber have been performed under the condition of optimum water content and maximum dry density. Both the content and length of basalt fiber are considered in this paper. When the

The major principal stress is horizontal with a magnitude of 3.4 MPa, and the compressive strength of the rock types is 53 MPa for the shale and 71 MPa for the basalt. The strength/stress ratio for these two cases is then 53/3.4 15.6 and 71/3.4 20.9, respectively, and so for both of them the stress reduction factor is 1.0.
Eight granite samples (18) are used for uniaxial testing. 13 are monotonically loaded with a rate of 2 mm/min. The axial stress rate approximately ranges between 0.15 and 0.25 MPa/s. Monotonic quasistatic uniaxial tests are performed to determine the uniaxial compressive strength (UCS) of the granite samples. Rock strength and porosity have good correlations for various rocks, and porosity can be obtained from lab tests or from density and sonic logs. In the following equations, the rock strength UCS is in MPa and porosity is in percent (%). For shales in the North Sea (geologically young and weak shales, mostly high-porosity Tertiary shales), Horsrud (2001) proposed the
The unconfined compression strength (UCS) is a funda-mental parameter that is often costly, difficult, or even impossible to determine through normalized testing 1, 2, 3 however, it may be determined with a simple geologist hammer or with the Schmidt hammer, among others 3. But for more approximate values it may be Another practice that is normally followed is to base the allowable pressure on the unconfined compressive strength, qu, of the rock obtained in a laboratory on a rock sample. A factor of safety of 5 to 8 is used on qu to obtain qa. Past experience indicates that this method is satisfactory so long as the rocks in situ do not possess extensive ...
