Repair Protection & Maintenance of Concrete Structures

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

Course Objective
 To identify the many advances in technology that have occurred and how they can provide
considerable benefit to the concrete rehabilitation
 To identify many types of mistakes that have often caused major disputes or conflicts and have
usually resulted in costly remedial work.
 To understand the critical characteristics of a given structure
 To understand the types and causes of common deficiencies (even failures) of structures
 To explain methods of observation, instrumentation and testing
 To workout preventive measures to counteract deterioration of structures
 To comprehend workable temporary and permanent repairs for any particular structure
 To provide a comprehensive practical guide on the practice and business of assessment of site
conditions and evaluation and repair strategies and techniques of concrete structures, or others
 To understand the nature of innovative technology
 To provide an overview for the role of effective management
 To comprehend the role of the designer, the contractor and the supervision in producing sound
 Determine means and ways for rehabilitation existing concrete structures.
