Assessment Of Defects In Concrete Structures and Evaluation Of Safety Of Concrete Infrastructure Course

Course Description

This course aims at providing participants with the knowledge, skills and expertise to identify durability problems of concrete structures, understand their causes, assess the associated short and long-term risks, and develop cost-effective and technically efficient rehabilitation and repair strategies to upgrade the performance of such structures, with special focus on hot and humid environments.

Course Objective

Specifically, participants will learn how to:

• Identify performance and durability problems of concrete materials and structures
• conduct field monitoring and non-destructive evaluation of concrete structures
• carry out forensic assessment of deteriorated concrete structures
• design repair strategies for deteriorated concrete structures including repairing with
• composites
• design stabilizing and strengthening techniques of reinforced concrete structural elements.
