Learning outcomes
Knowledge

Knowledge of the fundamentals of chemistry to understand the chemical phenomena and processes in the civil-construction engineering field. Knowledge of the different classes of materials used in this sector (metal alloy, ceramics, glasses and polymeric material). 

Assessment criteria of knowledge

Classroom exercises with questions to students and final exam.

Skills

Ability to identify the fundamental relationships between structure and properties of the main building materials in order to acquire an early skill in choosing and evaluating the most suitable material for a given application. Ability to define the most suitable material considering the degradation processes occurring in a specific environment.

Assessment criteria of skills

Questions during the lessons and final oral test.

Behaviors

The student will be able to acquire and/or develop a first skill in choosing the materials with the required mechanical properties and durability requirements. The student will be able to acquire some knowledge of the chemical risks associated with the use of specific materials, concerning environmental pollution, and the correct treatment of waste.

Assessment criteria of behaviors

Questions during the lessons and final oral test.

Prerequisites

Basics of mathematics according to high school programs.

Teaching methods

During the lessons, students are often involved with questions and invited to stop the teacher if the explanation is not clear and further information is needed. The main contents of the lessons are provided to students as supplementary teaching material. Textbooks are suggested and the solutions of many of the exams are available.
