Main causes of damage to engineering structures
Reinforcement of engineering structures using composite materials

The physical properties and, more specifically, the mechanical behavior of [15] concrete and steel are likely to deteriorate as a function of the environmental conditions defined by the geographical location of the structure.

The main causes of ageing are linked to the following phenomena:

• erosion, abrasion, impact ;

• action of freeze-thaw cycles ;

• physico-chemical alteration of concrete ;

• concrete shrinkage ;

• corrosion of metal reinforcements.

• Erosion, abrasion and impact

  Structures subject to erosion are mainly located in river and sea environments. They are subject to the...
