Table 3 Summary of results obtained by various methods in this work
Methods | Sample preparation | Results obtained in this work |
|---|---|---|
Ruxton method | Complex | Rough estimation, less than 1 cm |
Ultrasonic velocity test | Complex | Rough estimation, less than 1 cm |
Porosity analysis | Complex | Rough estimation, less than 1 cm |
Vapor absorption | Complex | About 7 mm. Accuracy is strongly affected by the sampling procedure |
Drilling resistance | Simple | About 7 mm. Heterogeneity of stone leads to the high variability of the drilling results |
Pore size distribution analysis | Simple | About 6.7 mm. Accuracy is less affected by the sampling procedure |
