The Estimation Of Uniaxial Compressive Strength Conversion

In the literature, conversion factors on different sedimentary, igneous and metamorphic rocks can be found, but no study exists on trona. In this study, laboratory UCS and field PL tests were carried out on trona and interbeds of volcano-sedimentary rocks. Based on these tests, PL to UCS conversion factors of trona and interbeds are proposed.

The estimation of uniaxial compressive strength conversion

The Estimation Of Uniaxial Compressive Strength Conversion

The point load PL test is generally used for estimation of uniaxial compressive strength UCS of rocks because of its economic advantages and simplicity in testing. If the PL index of a specimen is known, the UCS can be estimated using conversion factors. Several conversion factors have been proposed by various researchers and they are dependent upon the rock type.

For example, the PLT to UCS conversion factor can vary from as low as 8 to as high as 30, while the ITS to UCS conversion factor values vary between 2.7 and 50 43,44. This implies that the conversion factor is a rock characteristic parameter and not a universal value therefore, its applicability must be assessed on a case by case basis.
