Abstract

The archaeometric study of several mortar samples of the Pisa s Cathedral apse allows us to identify eight types of aerial and hydraulic binding materials, containing cocciopesto, fluvial sand, pozzolana, calcarenite and marble in various proportions bound by both aerial and hydraulic lime. The binder fraction is dirty snow-white in colour, with inhomogeneous structure due to the presence of millimetric lumps, in the cases in which only aerial lime is present and more or less whitish, reddish, pinkish or brownish in colour when binder is showing an hydraulic character.
