Materials play a major role in civil design and for this reason "Technology of Construction Materials" intends to provide a thorough engineering culture on building and civil engineering materials. In addition to theoretical insights, the course shows many applicative uses of materials in order to stimulate students ability and critical sensitivity on how material properties constitute a crucial information for the selection of an optimal materials and processing route for the realization of civil engineer structures. Technological processes for materials production and for the optimization of their properties will also be illustrated in details.

Technological processes for materials production and for the optimization of their properties will also be illustrated in details.
The overall aim of the course is to provide the students with a robust background in construction materials, encompassing both scientific and technological knowledge and providing general guidelines for translating scientific knowledge into an effective tool for civil engineering design. The student will learn: - how scientific principles are exploited in controlling relevant properties of construction materials; - the international (English) nomenclature and terminology; - the main international standards for the definition and characterization of constructions materials; - how to select materials to fulfill design and project requirements; - how to evaluate material properties, and to plan material testing activities, for both purchasing and quality control activities.
