- •
UPV and Schmidt Hammer were used as NDTs for strength estimation of building stones.
- •
Reliability in the stone strength assessment by the use of microcores was studied.
- •
Regression analysis and analysis of variability of the results were performed.
- •
UPV gives the best results in detecting strength variation among blocks.
- •
Results evidence some limits in the use of Schmidt Hammer and test on microcores.
