  • Teaching Mode: Traditional lectures (Modulo 1) Traditional lectures (Modulo 2) Traditional lectures (Modulo 3) Traditional lectures (Modulo 4)
  • Campus: Bologna
  • Corso: First cycle degree programme (L) in Civil Engineering (cod. 8888)

Learning outcomes

During the course, the basic principles of chemistry and stoichiometry, of the chemical and structural characteristics of matter and of the energetic and kinetic aspects of chemical transformations will be illustrated. The course also aims to provide the necessary tools for the rational evaluation of the uses of building materials in the building process: the student will acquire knowledge of the main physical-mechanical characteristics of building materials, finalizing the choice of materials, as well as their performance, also to the durability of the work.

Course contents

Requirements/Prior knowledge

A prior knowledge and understanding of the Chemistry Unit is required to attend with profit the Materials Technology Unit.

Fluent spoken and written Italian is a necessary pre-requisite: all lectures and tutorials, and all study material will be in Italian.

Teaching methods

The lessons will be given in blended way (and however according to the rules related to the pandemic emergency).

Chemistry Unit: The course is composed by theory and exercises; in the latter, students will be helped in solving exercises regarding stoichiometric calculations, balancing of redox reactions, calculation of reaction heat to cite some examples.

Materials Technology Unit: Frontal lessons. Exercises. Laboratory on binders and concrete.

Assessment methods

The exam is a written test. It is composed by quiz (typically 32), theory questions and exercises on topics covered by the program. The final test aims to evaluate:

- the knowledge of the atomic structure and relevant properties in three states of matter, with special focus on solid state

- the knowledge of resolution methods for fundamental chemistry problems

The grade of the written test is based on the evaluation of theoretical answers and exercises resolution.

The final test of Materials Technology unit is based on an oral examination, which aims to evaluate:

- the knowledge of the physical-microstructure characteristics of the most used building materials in Europe and their durability

- the knowledge of the mechanical properties of the most used building materials in Europe

The grade of the oral test is based on the evaluation of all the answers.

The final grade is calculated by CFU-weighted average of the grades obtained in the two different units (Chemistry unit + Technology of Materials unit).

The test dates for the whole year and the registration lists are available on-line on the official AlmaEsami website (the lists are closed 48 hours before each exam date).

Teaching tools

Frontal lessons with the use of blackboard and computer (images and videos are used to support lessons). 1-2 laboratory classes will be organized in the Materials Technology Unit.

In the Materials Technology unit, tests and exercises will be given during lessons for students' self-evaluation purpose.
