INNOVATIVE MATERIALS FOR CIVIL ENGINEERING
Lectures in Italian.
The course aims to provide the basic knowledge of the technological properties and usage of materials employed in structural engineering with particular reference to the acquisition of technical expertise in relation to the correct choice of materials and techniques used in engineering applications, as well as in the supervision of works and testing.
Understanding the terminology used in conventional materials and manufacturing and processing technologies.
APPLY KNOWLEDGE AND COMPRESSION
The student is provided with basic knowledge about:
- structure and technological features of materials for civil engineering;
- use of traditional and innovative materials for civil engineering.
The general method provided allows to understand the relationships between these themes and to organize them into a coordinated system of knowledge
AUTONOMY OF JUDGMENT
Ability to critically evaluate design choices in relation to the materials used and to be able to propose the appropriate solutions in terms of properties and durability.
Be able to dialogue using the correct technical terminology; be able to collaborate with other professionals for the development of multidisciplinary work; to motivate the design choices made in relation to the use of building materials.
Communicate with competence information, ideas, problems and solutions; know how to apply the acquired knowledge to different contexts from those presented during the course, and to deepen the topics discussed above with reference to evolution and innovation in the field of building materials.
The student must have acquired and assimilated the basic engineering knowledge from the Bachelor Degree.

The final exam consists of a written and oral test and is intended to ensure the acquisition of the knowledge and skills acquired during the course.
It can be taken in English by non-native speakers of Italian.
The written exam consists of open or closed questions regarding topics taught during lectures or during the exercises and present in the assignments provided to the students.
During the oral exam, which will last from 20 to 40 minutes, will be evaluated the level of theoretical knowledge acquired during the course and the ability to apply it in different civil engineering contexts. Finally, the level of communicative abilities and the clarity of the exhibition will be taken into account.
For the purposes of the evaluation, account is also taken of group practice exercises during the semester, with particular emphasis on the critical capacity with which the students addressed the proposed subject.
