SCIENCE AND TECHNOLOGY OF MATERIALS
Learning outcomes of the course unit
Knowledge and understanding:
At the end of the course the student will integrate his knowledge of base chemistry with the typical application of civil engineering, will have a complete overview of building materials in relation to their chemical composition, their structure and characteristics of use. He will have a basic understanding of the performance of materials and of the mix design.
Applying knowledge and understanding:
At the end of the course of study the student will develop the ability to choose the best material for the desired applications. He will be able to predict physical and chemical processing to be implemented on materials in order to modify the structure to improve its properties. He will also be able to put in place the appropriate measures to prolong the life of the material. The student will also be able to predict the controls to be carried out to verify that the materials used meet the desired characteristics.
On passing the exam, the student should have developed the ability to critically evaluate the analytical data of the mechanical behavior of a material to predict the behavior in work, as well as the ability to interpret the data of the controls for acceptance of a material to be used.
On passing the exam, the student should have acquired sufficient command of the language, at least as regards the technical terminology and specific chemical teaching.
The final seminar activities are designed to introduce students to the latest developments in terms of research in the field of materials science applied to civil engineering: the student should have acquired the knowledge and basic skills of discipline to deal with, in the future, an independent deepening of these aspects.
General and Inorganic Chemistry, fundamentals of Organic Chemistry are required. CHEMISTRY course is propedeutical.

The course is divided into a series of oral lessons using front projection transparencies.
Assessment methods and criteria
The final exam will be a written test in order to verify the ability of students to apply what they studied in numerical problems.
Written examination (up to one hour and a half) consists in 14 questions with closed responses (1.5 points per question) and three numerical exercises (3 points each). Students who gained at least 18/30 in the written examination are admitted to the mandatory oral examination which consists in answering to two questions. The final grade is a weighted average of the two oral and written exams.
It's strongly advised to attend the course.
