Learning outcomes
The course aims at giving the expertise to interpret the correlations between atomic/molecular structure, microstructure, macrostructure and behavior of materials; to acquire both the theoretical and practical aspects of the main techniques for physical, chemical, morphological and mechanical characterization of materials; to know the production technology, the properties and durability aspects of the different materials used in Civil and Environmental Engineering.

Program
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
LEARNING EVALUATION METHODS
Oral examination. To answer some questions, if necessary, short calculations will be carried out by the student during the oral test.

LEARNING EVALUATION CRITERIA
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.

LEARNING MEASUREMENT CRITERIA
Attribution of the final mark in thirtieths

FINAL MARK ALLOCATION CRITERIA
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.
