== Abstract ==

In order to investigate the mechanical behaviour of the typical ancient rubble stone
masonry type at the archaeological Pompeii site, an experimental program was carried out on
masonry panels realized with the aim of reproducing the ancient technique opus incertum.
Three panels (1.20m x 1.20m x 0.45m) were realized by using original rock units from ruins
emerged in the excavation works at Regio V at the site and pozzolanic lime-based mortar
realized according to the traditional technique. The first phase of the experimental program
involved the accurate reproduction of Pompeii-like masonry panels and the execution of sonic
pulse velocity tests to be compared with those carried out on original structures at the site.
Thus, three in-situ diagonal compression tests were carried out to derive masonry shear
strength and relevant correlation with sonic velocities. The last phase of the experimental
program focuses on laboratory axial compression tests on five specimens extracted from the
three panels analyzed in the first phase and is herein described in detail. The results of axial
compression tests on two of such specimens in terms of axial compression strength and elastic
modulus as well as the analysis of the crack pattern and failure mode is herein presented and
discussed.
