Materials play a major role in civil engineering design and for this reason the course "Degradation of construction materials and prevention" intends to provide a thorough engineering culture on building and civil engineering materials. L’insegnamento si pone l’obiettivo di fornire la preparazione teorica e pratica relativa al comportamento in esercizio dei materiali, necessaria per la realizzazione di nuove costruzioni e per il restauro di quelle esistenti. Si affronteranno i temi seguenti: a) il degrado dei materiali e delle strutture in funzione delle condizioni di esposizione ambientale, b) la prevenzione in sede di progetto, costruzione e gestione delle strutture, c) le tecniche di indagine sui materiali e sulle costruzioni (diagnostica e analisi del degrado), d) i materiali e le tecnologie per il consolidamento e restauro delle opere degradate The course also shows many applicative uses of materials in order to stimulate students ability and critical sensitivity on how material properties constitute a crucial information for the selection of an optimal materials and processing route for the realization of civil engineer structures. Technological processes for materials production and for the optimization of their properties will also be illustrated in details.
Materials play a major role in Civil Engineering and, for this reason, the course “Degradation of construction materials and prevention” aims at providing a thorough engineering culture on Building and Civil Engineering materials, with a special focus on degradation issues. The course will provide a theoretical and practical overview of the operating behavior of materials, which is key for the construction of new buildings and the restoration of existing ones. The following topics will be specifically addressed: i) degradation of materials and structures as a function of environmental exposure conditions, ii) prevention strategies in the design, construction, and management of structures, iii) investigation techniques on materials and constructions (diagnostics and analysis of degradation), iv) materials and technologies for the consolidation and restoration of degraded structures. The course will also show many applicative uses of materials in order to stimulate student’s ability and critical sensitivity on how material properties constitute crucial information for the selection of optimal materials and processing routes in Civil Engineering structures. Technological processes for materials production and for the optimization of their properties will also be illustrated in detail, when relevant.
Al termine dell’insegnamento, lo studente sarà in grado di: - conoscere i meccanismi di degrado ai cui possono essere soggetti i materiali da costruzione, sia metallici sia non metallici, in funzione delle condizioni di esposizione ambientale; - utilizzare le conoscenze teoriche acquisite su questi materiali da costruzione per valutare lo stato di degrado e la durabilità di strutture realizzate con essi; - individuare i metodi e le tecniche più adeguate per la prevenzione dei fenomeni di degrado dei materiali da costruzione in sede progettuale; - discutere e individuare le prescrizioni sui materiali e i metodi di controllo da adottare in sede di esecuzione e manutenzione delle strutture.
At the end of the course, the students will be able to: - know the degradation mechanisms which are typical of both metallic and non-metallic construction materials, depending on the materials inherent properties, specific service, and environmental exposure conditions; - use the theoretical knowledge acquired on these building materials to evaluate the state of decay and durability of structures; - identify the most suitable methods and techniques for preventing the degradation phenomena of construction materials in the design phase; - discuss and identify the requirements and good practices on materials as well as the control methods to be adopted during construction and for the maintenance of the structures.

Exam: Written test;
Written exam. Objectives that will be ascertained by the exam, consistently with the expected learning outcomes: the exam aims at verifying the comprehension of the theoretical and applicative topics given during the lessons, with a special focus on degradation and interaction between materials and environment. Specifically, the exam will verify the student’s capability to read technical diagrams and relate the information included in such diagrams with operative/service performance of materials, to identify the properties of materials useful for specific applications, to critically select the most suitable materials for specific applications, to forecast degradation phenomena and plan suitable prevention/restoration actions. Criteria, rules, and procedures for the exam Individual written test, consisting of 1 or 2 open questions and 4 multiple-choice questions on metallic materials, and 1 or 2 open questions and 4 multiple-choice questions on non-metallic materials. Multiple-choice questions can have 1 or more correct entries. The total duration of the exam is around 60 minutes. In replying to open questions, the students are requested to clearly justify their design choices, materials selection, prevention/restorative intervention. No additional penalties will be applied to incorrect responses to multiple-choice questions. The evaluation includes all lecture topics. Textbooks, lecture notes, formularies, and electronic devices cannot be used during the exam. The maximum score that can be achieved by the students is 30/30 cum laude.
In addition to the message sent by the online system, students with disabilities or Specific Learning Disorders (SLD) are invited to directly inform the professor in charge of the course about the special arrangements for the exam that have been agreed with the Special Needs Unit.
