Experimental assessment of shear strength parameters on rubble stone
The failure by stone crushing explains the similitude between the strength of the two specimens and, also, the unusually high compression strength obtained for both types of masonry. This effect would probably be diluted in a larger specimen, where it would be felt a larger influence of the mortar quality.
