Superfici materiche nella percezione della scena urbana

2013

La percezione della scena urbana: superfici architettoniche. Gli interventi d’alterazione corticale nelle architetture dei centri minori del Parco delle Madonie modificano progressivamente il paesaggio urbano nei centri antichi. La parte più esterna di materia veicola l’immagine delle architetture e possiede un ruolo essenziale nella percezione dei quartieri storici che ancora caratterizzano i centri della riserva naturale; ma la tendenza a rimuovere le finiture storicizzate e le patine del tempo comporta l’alterazione irreversibile del carattere dei centri antichi. Doveva essere ovvio che sarebbe stato essenziale conservare i segni del tempo, che denotano l’autenticità materiale della part…

Le superfici di pietra artefatta. Conoscenza e diagnosi per la conservazione.

2009

La tesi di dottorato è incentrata sullo studio delle finiture architettoniche di pietra artificiale realizzate con metodi o ricette coperte da brevetto in Italia. La ricerca, dopo avere descritto le ricette e metodi per simulare le pietre naturali, propone una metodologia analitica diagnostica per la conservazione delle superfici architettoniche e mostra gli esiti delle sue applicazioni sperimentali. The PhD thesis is focused on the study of architectural finishes of artificial stone patented in Italy. The research, after presenting the recipes and methods to simulate natural stones, proposes an analytical diagnostic method for the conservation of architectural surfaces and shows the result…

Experimental evaluation of plasters durability aimed at maintenance planning and scheduling

2011

The phase of building management has a strategic importance because of the necessary scheduling of maintenance during executive planning. Moreover, in order to obtain the greatest sustainability of the intervention, a reasonable duration of service life must be balanced with global quality-cost ratio. A contribution towards this objective is given by the reduction in the achievable resources and raw materials consumption through the improvement of the durability requirement of building and its parts. This is true even for the interventions on the existing public building stock, especially if there is lacking of maintenance planning and scheduling. This work, taking cues from a maintenance i…

Life Cycle Assessment and eco-design of building materials: the case study of a Sicilian cement plaster

2015

Buildings in the European Union (EU) account for the largest share of the total EU final energy consumption (42%), and greenhouse gas emissions (35%). Therefore, the reduction of energy use, the development of quality-oriented processes and the improvement of energy performance in the building sector are important measures needed to reduce greenhouse gas emissions and the energy dependency of the European Union from foreign countries. In this context, it is necessary to develop sustainable building products, with low energy and environmental impacts during their life cycle, from the extraction of raw material to the manufacturing, use and end-of-life. The main goal of the study is to define…

Validity and reliability of measurements of the parameters of smile aesthetics: a comparison between digital and plaster models

2020

This study aims to evaluate the validity and reliability of the TRIOS3 Color intraoral scanner (3Shape A/S, Copenhagen, Denmark) and its associated Ortho Analyzer™ software in measuring parameters of smile aesthetics compared with measurements on plaster casts. The study sample comprised plaster casts and digital models obtained from 30 subjects. Height (H), mesiodistal diameter (MDD) and connecting space (CS) of the anterior teeth were measured with a digital calliper on the plaster models and with the orthodontic software on the digital models. Validity was assessed using a 2-tailed paired t-test; the reliability of measurements for intra-examiner was evaluated with the Intra-class Correl…

L'intonaco Li Vigni nell'architettura del XX secolo a Palermo. Nuove conoscenze e applicazioni diagnostiche per la manutenzione

2013

Il saggio presenta lo studio degli intonaci formulati per imitare le pietre e i marmi naturali che si diffondono in Sicilia all’inizio del XX secolo ed evidenzia che le prime applicazioni e la diffusione delle nuove malte, anche nel resto dell’Italia, risentono delle sperimentazioni condotte in tutta l’Europa. Il contributo riassume i risultati di una rigorosa e capillare ricognizione tra i brevetti conservati presso l’Archivio Centrale dello Stato a Roma inerenti alle malte per il confezionamento dell’intonaco a “finta pietra”, ne analizza i contenuti in modo critico e pone in risalto i contatti culturali con le sperimentazioni dei materiali in atto nell’ambito dei grandi cantieri di resta…

The paper presents the study of the plaster formulated to imitate the natural stones and marbles that are popular in Sicily in the early twentieth century and points out that the first applications and the dissemination of new mortars also in the rest of Italy feels the influence of the experiments conducted throughout Europe . The contribution summarizes the results of a rigorous and thorough reconnaissance of patents kept in the Archivio Centrale dello Stato in Rome relating to mortars for plastering an artificial stone critically analyzes the content and emphasizes cultural contacts with the experiments on large-scale restoration projects in Italy and France in the late nineteenth century. The analysis of the architectural surfaces is developed with instrumental tests: the levels of adhesion of finishing surface are characterized in particular through a campaign of thermographic investigations and diagnosis is drawn to show that the consolidation of the layers and reintegration are interventions to be introduced ​​within the restoration project and maintenance program.Settore ICAR/19 - Restauro
