Conoscenze e abilità da conseguire
During the course, the basic principles of chemistry and stoichiometry, the chemical and structural+ characteristics of matter and the energetic aspects of chemical transformations will be illustrated. Moreover, the course provides the tools for evaluating and selecting the materials to be used in buildings: students will learn the main chemical, physical and mechanical properties of most used building materials, as well as their technical characteristic and durability in different working environments.

Metodi didattici
Frontal teaching.
During the lessons will be carried out exercises of the same type and difficulty than those that will be submitted to the students during the exams.
Modalità di verifica e valutazione dell'apprendimento
The examination is divided into two separate verification tests: one of chemistry and one of materials technology.
The Chemistry exam takes place through a 90-minute written test with multiple choice questions, open questions and numerical exercises.
The Materials Technology exam takes place through a 90-minute written test, structured in two open questions, five multiple choice questions and a numerical exercise.
Both exams will focus on the main topics of the lesson
During the verification test, the use of books, notes and any type of electronic device (smartphone, tablet or similar) is not allowed.
The overall result, achieved if both the chemistry and materials technology tests result at least sufficient, will be the average of the results obtained in the two tests.
Although it is strongly recommended that the two tests are carried out in the shortest possible time, there is no time limit to complete the examination in its two parts.
Strumenti a supporto della didattica
The slides projected during the lessons will be available online on the Virtual platform.
For a better use of the lessons, the slides should be printed and taken to the classroom.
Take care: the slides provided, even if supplemented by the notes taken in class, do not replace the reference texts.
