Introduction
Over the last decade, concrete rehabilitation has become recognized to be a “stand alone” discipline
requiring very specialist knowledge and expertise. This course has been developed to cover the latest
advances in materials and techniques and the current state-of-the-art for the rehabilitation of concrete
structures. Various concrete deterioration mechanisms will be identified, together with the way in which
failure to understand them can impact on the development of a rehabilitation strategy.
Structural dysfunction (even failure) is not just an accident. It is the result of human error originating
from oversight, carelessness, ignorance or plain lack of knowledge. Early savings in design and
construction costs often boomerang as later and larger costs of repair and litigation.
In short, structural malfunction may be characterized as the unacceptable difference between intended
and actual structural performance. We must conclude that in the field of structures, as in any other field
of human endeavor, only better knowledge and a deeper consciousness of our professional, human and
social responsibilities can lead to the construction of safer and better performance buildings.
Sound knowledge can also help us with the proper means to maintain and rehabilitate deficient
structures when the need arises, eventually extending the lifespan of structure and leading to better
performance under service conditions.
