Analysis and characterization of hydraulic mortars from ancient cisterns and baths in Greece
Abstract Structural mortars and plasters from cisterns and baths (thermes) from Roman, Byzantine and Ottoman period in Greece are analyzed in terms of their physico-mechanical, chemical, and microstructural characteristics, in order to find the key factors for their functionality. From the analysis it is found that their coherent and dense structure is due to the action of different mechanisms caused by the selection and combination of raw materials and the interaction with the special environment into which they served. The binding system is mixed, with the combination of hydrated lime and materials with pozzolanic properties. The aggregates are both siliceous and brick fragments of different granulometry, according to the mortar’s type (structural or plaster). The raw materials used as binders and aggregates and the technology practices during mortar application contribute to low porosity mortars with dense structure. Additionally, the environment of the cisterns and baths functioned on the benefit of the materials, as it favored the dilution of the calcite and the secondary phases formed in the mortars’ porous nature assisted towards the cohesiveness of their structure. The technology used for the production of mortars applied in baths and cisterns for a long period of time proves the high knowledge of materials’ behavior in order to produce durable constructions, resistant to highly deteriorating factors.
