Abstract: In this paper an experimental study conducted on Red Clay brick masonry triplets built with Cement- and Hydraulic Lime-based mortars is presented. Monitoring of fracture is conducted by Acoustic Emission (AE) and Digital Image Correlation (DIC). Representative masonry triplet elements are tested in shear for investigation of the fracture mechanisms in relation to the properties of different mortars. The results complemented by DIC, accurately showed the location of macro cracking and the developing of strain concentrations even before fracture. For complete profound understanding of individual properties, small scale experiments were also conducted on masonry components for characterization of AE signatures.
