By the durability of individual building materials and of the structures built of
them, it is the time of usability under preservation of their original properties is
The words corrosion and deterioration are primarily derived from this
Corrosion is applicable to metals, reinforcement and polymers.
building materials such as concrete, plasters, mortars, we use the term deterioration.
Deterioration of concrete is a gradual and irreversible permanent erosion of its
basic properties leading to its disintegration.
The study of concrete and building
material deterioration and durability and the knowledge of these properties form
the fundamental basis for the evaluation of structures.
The durability of structures is
influenced by many factors.
The general defects and failures of building structures
can be divided into the following (see Fig.
• deterioration by the environment,
• defects and failures in design and in completion of structures,
• unsuitable design,
• bad quality of material,
• bad execution, and
• failures caused by inappropriate utilisation.
Defects and failures of buildings can be eliminated by proper control of products
and execution of construction, and inappropriate utilisation of materials can also
Generally, we cannot influence the environment much.
