Abstract
In split cube geometries the specific fracture energies of sandstone-m ortar (14 Nm(-1)) and limestone-mortar (6 Nm(-1)) interfaces were dete rmined. They are much lower than for bulk mortar (80 Nm(-1)), A damage type law describes well the development of a process zone around the interfacial cracks. In finite element calculations the damage law desc ribes the behaviour of flat interfaces, but needs improvement for curv ed interfaces.
