Abstract

The present work attempts to fill the gap in knowledge on the behaviour and durability towards atmospheric multipollutants of hydraulic mortars used as a construction material in buildings and monuments. Different types of ancient and recent hydraulic mortars were collected from the Arsenal in Venice. A summary of the characterization of the samples is presented, along with the identification of the formation products found on the surfaces due to the reaction between the mortars and atmospheric multipollutants. A series of analyses was performed by means of optical microscopy (OM), X-ray diffractometry (XRD), scanning electron microscopy (SEM-EDX), thermal analysis (DTA-TGA)
