Abstract
This paper aims to characterize historical mortars taken from joints in Loom Factory site atAbydos Sohag (Egypt). This characterization includes their composition and technology, theirstate of preservation as well as provides a guide for their possible conservation process. Amultidisciplinary approach has been adopted for investigations. Samples were investigated bymeans of visual inspection, polarizing microscope (PM), scanning electron microscope (SEM)coupled with energy dispersive X-ray unit (EDX), powder X-ray diffraction (XRD), hydrochloricacid (HCl) attack, sieving analysis, deferential thermal analysis (DTA-TG) and physical tests.Obtained results allowed to fully characterize mineralogical, chemical, and mechanicalproperties of selected mortar samples. They show a similarity of type, and binder/aggregateratio. This similarity can be attributed to one building phase using the same source ofmaterials.
