El Tel revealed he had to say no due to hip problem Within the dataset of this study, the 15 tuffs show a wide range of different responses and resistance towards salt weathering (Table 3). An overall trend indicates that, on average, crystal tuffs obtain lower resistance (11–109 salt cycles; mean 47 cycles) and vitric tuffs higher resistance (39 to > 150 salt cycles; mean > 83 cycles). Petrophysical properties and weathering behavior: bivariate analysis Salt bursting tests identify the resistance of the material to crystallization pressure of salts. Sousa et al. ( 2018) give a detailed overview on controlling factors of salt weathering in granitoids. López-Doncel et al. ( 2016) investigated the main factors influencing the salt weathering in volcanic tuffs. A critical literature review on salt crystallization tests and new ideas to overcome existing limitations can be found in Lubelli et al. ( 2018b). In many investigations, especially in timely limited thesis works (e.g., Molina-Maldonado 2016; Teipel 2020; Wittenborn 2015), the salt bursting tests are not continued after a certain amount of cycles and results are extrapolated from the status quo. Individual stones, however, may show significant deterioration only after a high amount of cycles (e.g., Pötzl et al. 2018b; Sousa et al. 2018). An extrapolation of the results may be reasonable within individual datasets, but does aggravate the overall comparability with the results of other studies. Some studies extrapolated after 40 cycles; others stopped testing after 150 cycles. The illustration of the range of absolute values in form of a boxplot is therefore misleading and was consequently not done in this study.

Both porosity and bulk density have a strong relation to the ultrasonic velocity, which in turn shows to be a good estimator for the strength of tuffs. This observation is not trivial, since tuffs can incorporate huge amounts of pumice clasts and lithics, that may considerably influence the propagation of the P-wave, e.g., due to increasing the pore space. Therefore, an ultrasonic testing device can help for a fast and non-destructive assessment of the materials’ quality parameters, like it is reliably done for more homogenous natural stones and concrete (Sharma and Singh 2008).
