Abstract
The aim of this research was mainly to investigate teh binder composition of several kind of ancient mortars in order to understand the reason of such good mechanical characteristics. The problems that arise when investigating the binder portion of a mortar are well known from literature and depend mainly because the difficulty in the separation of the binder from the aggregate. Moreover, often the components of the binder do not completely crystallise so that the usual methodologies (i.e. XRD) are not realiable. In this work the problem of the binder characterisation was faced utilising different methodologies: TG, XRF, and XRD analyses were carried out on the binder portion separeted from the aggregate through mechanical breaking up and following sieving of the portion < 63 micron (binder); EPMA analysis was carried out on the binder portion visible in thin section. At present these methodologies are utilised as routine work but the particular application that we propose for EPMA could be useful for a correct characterization of a mortar binder.
