Obiettivi dell'insegnamento

The course aims to provide the basic principles for the correct use of materials in the civil engineering. Starting from the structure and the properties of the different classes of materials, the course provides the instruments for the rational choice in terms of mechanical, physical and durability properties. Particular attention is paid to the study of cementitious materials and steels, due to their relevance in the construction sector. The course also covers other construction materials, as timber, traditional ceramics and glasses. 

 


Risultati di apprendimento attesi

Lectures and exercise sessions will allow students to:

- understand the relationships between the structure, the properties and the applications of different classes of materials;

- understand the differences among the different classes of materials and, in particular, among the different concretes and steels; 

- choice the more suitable materials as a function of the requirements required by a specific application, in order to employ them correctly in the design in the civil field; 

- know the main European standards and codes related to construction materials.


Argomenti trattati

In details, the course covers the following topics. 

  1. Materials introduction. Main materials related to the field of civil engineering. Classification.
  2. Mechanical behaviour. Elastic behaviour; yielding; ductile and brittle fatigue; resilience; principle of fracture mechanics. Tension, compressive, flexural, hardness, Charpy and cyclic tests.
  3. Binder materials. Portland cement; raw materials and production processes; composition; hydration; setting and hardening; development of microstructure; heat of hydration; porous structure of cement pastes and its bounds with mechanical strength and permeability. Blended cements. Gypsum, lime and hydraulic lime (outlines).
  4. Concrete and reinforced concrete. Aggregates. Concrete admixtures. Fresh concrete: workability, segregation and bleeding. Hardened concrete: permeability, mechanical properties, hygrometric shrinkage, creep, cracking. Concrete degradation and steel reinforcement corrosion (outlines). Concrete prescriptions. Concrete mix design as a function of requirements of resistance, durability and workability. Special concrete (HPC, SCC, lightweight concrete).
  5. Metals and alloys. Crystal structure of metals. Strengthening Mechanisms. Metals in construction: steel reinforcement for concrete, pre-stressing steel, stainless steel, cast iron. Non-ferrous metals: copper and its alloys and aluminium. Forming of metals, shaping and finishing. Corrosion: mechanism, general and localized corrosion. Atmospheric corrosion and corrosion prevention.
  6. Ceramics and glasses. Clay products used in the construction field (brick, tiles, refractories). Main types of glasses: structure, properties and applications.
  7. Timber. Structure; anisotropic behaviour; density; humidity, defects; deformation, mechanical properties. Board materials.

Prerequisiti

Students are required to have or acquire basic notions on mathematical analysis, chemistry and physics.

 


Modalità di valutazione

Written examination (mandatory), oral examination is optional. 

The written test consists in:

  • multiple choice theoretical questions and, potential, an open question, aimed at assessing the student's knowledge and understanding of topics covered in the programme; 
  • numerical exercises, in particular on mechanical properties and concrete mix design aimed at assessing the ability of the student to apply the theoretical knowledge to typical design problems of civil engineering.

The oral exam consists in:

  • theoretical questions on topics covered in the programme;
  • questions intended to reveal the student’s ability to apply knowledge and understanding of the various topics covered in the program.

Knowledge and understanding: materials properties and their correlation with the structure. Ability to apply the knowledge and understanding: selection of the more suitable materials as a function of the requirements required by a specific application.
