Building engineering and architecture

1. Categories of materials Concrete. Structural lightweight concrete. Special concrete: SCC (self compacting concrete), HVFA (high volume fly ash concrete), HPC (high performances concrete). Recycled concrete. Special metal alloys. Stainless steel. Polymeric materials for building materials (additives, adhesives, paints and coatings). Soundproofing materials. Composite materials for construction: general informations, characteristics of matrices and fibers. Mechanical properties of composite materials. Short fiber composites. Long fiber composites. Wood. 2. Durability Corrosion and protection of metallic materials. Wet corrosion and dry corrosion. Corrosion in natural and aggressive environment. Durability of concrete and reinforced concrete: corrosion by carbonation, chlorides and sulphate action. Degradation and durability of polymeric materials and composites. 3. Conservation of materials Diagnostic techniques (destructive and non destructive) for the characterization of construction materials. Evaluation of diagnostic results for conservation of materials. Standards. Nor.Ma. L. and RILEM recommendations. The materials in historic buildings. Chemical – physical and biological mechanisms of degradation. Role of humidity in the processes of degradation. Materials and technologies for the restoration and consolidation.

Basic knowledge about materials science and technology. Knowledge about stress and deformations of materials with references to construction theory and technology.

The course is aimed at fourth year students of the master degree in Civil Engineering. It is a traditional course that provides classroom lessons with exercises. Laboratory exercises are also planned.

Attendance is not compulsory.

The exam consists of a preliminary written test and subsequent oral examination. Written test: two exercises (high performance concrete, mix design, correct choice of materials). Oral test: three question on theoretical aspects of materials technology and on standard tests. Only students with 18/30 at the written test are admitted to the oral test. Evaluation criteria for the written test: procedure correctness, numerical results accuracy, correct results interpretation.
