Learning outcomes
The course enables students to acquire the skills to interpret the correlations between atomic/molecular structure, microstructure, macro-structure and behavior of materials. Integrating the knowledge gained in the basic sciences courses, it allows to aquire the theoretical and practical basis for understanding the major physical-chemical, morphological and mechanical characterization techniques for building materials, and for diagnosis of their degradation. The course enables students to learn he methods of production, the properties and durability of different classes of materials used in civil and environmental engineering.
In order to address advanced design themes and treat the innovation and development of new products and new technological processes through the application of knowledge, the student should be able to correctly interpret the correlations between structure and properties of building materials. This will be reflected in a range of professional skills, such as: 1. the ability to choose the most suitable material for the realization of a particular structure in a given exposure environment; 2. the ability to analytically describe and appropriately interpret the results of laboratory tests on construction materials; 3. the ability to identify the causes of failure of a construction material working in a team with other elements involved in the study of the problem.
The course improve the ability to learn and draw conclusions independently, the ability to be concise, the independent judgment skills and communication skills promoting the use of an adequate technical and scientific language.

Correlation between structure of materials and their properties. Covalent, ionic, molecular and metallic solids. Comparison between classes of materials. Transport mechanisms in materials. The role of water as deterioration agent of porous materials. Durability and sustainability of materials. Chemical, physical, morphological and mechanical characterization of materials. Destructive and non-destructive testing. General properties of building materials and related applications: wood, raw earth, ceramic, glass. Historical evolution of binders: gypsum, lime, lime and pozzolana, hydraulic lime, Portland cement and blended cements. Hydration of cement. Aggregates: eligibility criteria, grain size; chemical additives: accelerators, retarders, superplasticizers, air-entraining agents, curing agents, water repellents. Fresh concrete: workability, compaction degree, bleeding and segregation, plastic shrinkage. Hardened concrete: curing, thermal gradients, differential expansion, drying shrinkage deformation and creep. Mix-Design. Durability of concrete and related normative. Steels: general purpose, quality, welding (steel for reinforced concrete and carpentry). Structure (Fe-C diagram), production and properties. Metal-environment interaction: introduction to thermodynamics and kinetics of corrosion, corrosion of reinforcement bars and metal structures. Polymeric materials: thermoplastics, thermosets and elastomers in construction. Composite Materials.

Development of the examination
Oral examination. To answer some questions, if necessary, short calculations will be carried out by the student during the oral test.

To successfully pass the examination, the student should demonstrate: how to interpret the correlations between atomic and molecular structure, microstructure, macrostructure and the behavior of materials, he has acquired the theoretical and practical bases for the physical, chemical and mechanical characterization of materials and to know the methods of production, properties and the main applications for the different classes of materials used in construction field.

Attribution of the final mark in thirtieths

In order to pass the exam with a minimum score the student should possess the full knowledge. Further score will be awarded based on the mastery of specific and general skills. The honors will be given to students who, having achieved the highest rating, have demonstrated a particular command of the subject with otstanding ability to connect the different contents of the course.
