65601 - Chemistry and Technology of Materials

Learning outcomes

The course aims to provide the tools necessary for the rational evaluation of the uses of building materials in the construction process and restoration. The student acquires the knowledge of the main physical and mechanical parameters of building materials and applies them in an autonomous way, finalizing the choice of materials also the durability of the work.

Teaching methods

Lectures. Some lessons will be dedicated to application drills

Assessment methods

The exam is divided into two separate verification tests.

Chemistry: the test consisting of a written part (multiple choice questions and simple exercises) and oral.

Materials technology: the test consists of a single oral test.

The oral examinations of chemistry and materials technology will be held the same day to give the opportunity, to those who wanted to, to hold both tests.
