From βαλανεῖα to thermae: unveiling the transition from Greek to Roman architectural models of baths by technological and provenance archaeometric st…
2019
So far unexplored, the introduction and the spread of the Roman thermal buildings in the prima provincia (Sicily) are widely debated in the current archeological studies. Mainly due to the lack of systematic excavations and intensively technological studies, the assessment of thermae in the Hellenistic-Roman Sicily has been thus far interpreted as a new social and architectural experience. However, a more careful archeological investigation would suggest a gradual transformation of the architectural landscape from the purely Greek bath tradition to the canonical thermae types. The aim of this paper is therefore to study the classical hot bath culture and, in particular, the transition from …
Alkali activated materials using pumice from the Aeolian Islands (Sicily, Italy) and their potentiality for cultural heritage applications: Prelimina…

Abstract In this paper, the potentialities of pumice-based geopolymers have been explored with the aim to evaluate their use as restoration materials. In particular, the behaviour of Aeolian pumice during alkali activation process, either alone or in binary mixtures with metakaolin, has been assessed using sodium hydroxide and sodium silicate activators. Hardened products were characterized by: X-ray diffraction; infrared spectroscopy; thermo gravimetry and electron microscopy. Furthermore, Hg-intrusion porosimetry, water absorption, compressive strength and colorimetric measurements were carried out in order to define the technical features of the produced geopolymers. The results reveal t…
