Roman buildings: mortar, hydraulic mortar and pozzolanic concrete in the Gulf of Naples, Campania –Italy.

Renata Esposito

Abstract


The article is intended to synthesize published information regarding carried out into mortar and concrete materials about roman buildings in the gulf of Naples, Italy.

The region for its geological formation and for the historical significance of Roman cities and its monuments is interested by multidisciplinary studies on the raw materials and  roman construction technologies for an in-depth knowledge of the composition of geomaterials degraded in time and Structural problems with a view to restoring the archaeological heritage.

The article presents the case studies of two geographic areas in particular, the sites of the Phlegrean Fields and the Vesuvian area (Puteoli, Baia, Misenum, Pompeii, Herculaneum, Stabia, Surrentum). The results indicated that complexes and monuments of importance have a composition of mortars and conglomerates which is found to match what is indicated by the sources and that malfunctions made in different chronological periods do not always retain the same composition.Forthermore results confirmed that Roman engineers extensively used local geomaterials such as volcanic and sedimentary aggregates mixed with hydrated lime.
