The point load index (PLI) test is one of the most frequently applied indirect methods in predicting the uniaxial compressive strength (UCS). Depending on the rock sample shape, the PLI test is performed in four procedures: axial, diametrical, block, and irregular lump tests. The present research aims to conduct a comparative study on the accuracy of these . The results of the comparative compression test on both un-polished and polished samples that produced the curves are presented in Figure 5. The values presented in Figure 6 reveal that un-polished specimens have a significantly lower compression strength than the polished samples for each of the tested composites, .
