THE COURSE AIMS TO PROVIDE KNOWLEDGE AND MANAGMENT OF PROBLEMS RELATING TO THE AGING AND DEGRADATION OF CONSTRUCTION MATERIALS. THEREFORE, IT IS INTENDED TO GRANT SKILLS IN THE FIELD OF DEGRADATION PHENOMENA, DIAGNOSTIC TECHNIQUES FOR ASSESSING THE DAMAGE AND METHODS OF RECOVERY AND STORAGE .

KNOWLEDGE AND UNDERSTANDING :
UNDERSTAND THE TERMINOLOGY USED IN THE FIELD OF MATERIALS TECHNOLOGY, THE IDENTIFICATION OF MATERIALS DECAY, THE DIAGNOSTIC TECHNIQUES AND THE REHABILITATION OF BUILDING MATERIALS .

APPLIED KNOWLEDGE AND UNDERSTANDING :
UNDERSTANDING AND IDENTIFICATION DEGRADATIVE PROCESSES; READING SKILLS OF DIAGNOSTIC RESULTS .

JUDGEMENT :
CAPACITY OF SET UP APPROPRIATE CHOICES AND METHODS OF INTERVENTION TECHNIQUES IN THE CONTEXT OF RECOVERY AND RESTORATION OF BUILDING MATERIALS .

COMMUNICATION SKILLS :
BE ABLE TO TEAM WORK AND TO MAKE ORAL PRESENTATION OF SPECIFIC TOPICS.
Prerequisites
FOR THE ACHIEVING OF THE COURSE AIMS IT IS REQUIRED THE BASIC KNOWLEDGE OF MATERIALS TECHNOLOGY.

ANALYTICAL AND DIAGNOSTIC TECHNIQUES.
PHYSICAL AND CHEMICAL ANALYSIS; LABORATORY EQUIPMENT AND TECHNIQUES. TESTS ON POROUS MATERIALS. TECHNICAL INSPECTION AND IN SITU INVESTIGA-TIONS. NON-DESTRUCTIVE TECHNIQUES.
Teaching Methods
THE COURSE IS STRUCTURED INTO THEORETICAL LECTURES AND EXERCISES BOTH IN THE CLASSROOM AND LABORATORY.
PRACTICAL PROBLEMS WILL BE PROPOSED IN THE FIELD OF THE ANALYSIS OF THE DURABILITY OF MATERIALS. LABORATORY EXPERIENCES WILL STRENGTHEN THE CONCEPTS ACQUIRED.
LECTURES ARE PROVIDED IN CLASSES IN THE PRESENCE OF STUDENTS.
IN PARTICULAR, THE COURSE IS STRUCTURED IN 35 HOURS OF THEORY, 10 HOURS OF EXERCISES HELD IN THE CLASSROOM, 15 HOURS OF LABORATORY PRACTICE..
THE MINIMUM FRACTION OF ATTENDED HOURS OF LECTURES REQUIRED TO TAKE THE EXAM IS 70%
Verification of learning
THE ASSESSMENT OF THE PREPARATION WILL BE PERFOMED AT THE END OF THE COURSE BY AN ORAL INTERVIEW WHICH IS INTENDED TO CHECK THE LEVEL OF LEARNING AND THE DEGREE OF COMPREHENSION OF THE ARGUMENTS. THE ASSESSMENT IS BASED ON THE LEVEL OF KNOWLEDGE ACQUIRED, ON THE CORRECTNESS OF EXPRESSION AND TERMINOLOGY, AND THE ABILITY TO CONNECTING CONCEPTS.

IN ORDER TO PASS THE EXAM, STUDENTS MUST AT LEAST BE ABLE TO IDENTIFY THE CAUSES OF DETERIORATION OF BUILDING MATERIALS AND POSSIBLE PREVENTION AND RECOVERY STRATEGIES.
THE LEVEL OF EXCELLENCE CAN BE REACHED BY STUDENTS WHO SHOW TO BE ABLE TO ADDRESS NON-STANDARD PROBLEMS OR NOT SPECIFICALLY PRESENTED DURING THE LECTURES, WITH PARTICULAR REGARD TO THE CORRECT APPLICATION OF THE CORRELATIONS BETWEEN STRUCTURE, CONSTRUCTION AND DURABILITY.
