Because preparing the desired smooth specimens from pyroclastic rocks is difficult for some standard tests, the development of some equations is important for predicting the uniaxial compressive strength (UCS) of these rocks. In this study, the relation between the UCS and block punch index (BPI) for pyroclastic rocks was investigated. Twenty eight different samples of pyroclastic rocks collected from the Cappadocia Region were tested in the laboratory. The linear regression analysis shows that the UCS-BPI conversion factor for the tested rocks is 3.0. On the other hand, the correlation coefficient of power law function is higher than that of the linear function. Concluding remark is that the UCS-BPI conversion factor for the pyroclastic rocks is lower than the suggested general conversion factor of 5.5 and the UCS-BPI relation is best represented by power law function.
