Aims :

The aim of the course is to give students a basic knowledge on mechanical performances and durability of concrete and ordinary steel, related to type of structure and environment.

Topics :

Fundamental Properties of Engineering materials
A
-Concrete: -requirements and features of Portland cement and blended cements; natural aggregates: characteristics and qualification, size and grading; chemical admixtures: retarding, accelerating, water reducing, air-entraining and curing admixtures.
-Concrete at early ages: workability; compacting factor; segregation and bleeding; plastic shrinkage.
-Hardened concrete: curing conditions; strength; drying shrinkage and creep; thermal stresses.
-Durability: classification of causes and EU normatives.
-Mix design: specification based on strength.
B
-Steels: ordinary steel, structural steel, welding steel. Stainless steel. UNI specification.
-Structure (Fe-C diag.; thermal treatment, production processes); mechanical properties.
-Metals and environmental: brief introduction on corrosion thermodynamic and kinetics; corrosion of reinforcement bars; atmospheric and underground corrosion of steel construction
