After participating in the seminar you will be able to do the following:
• use the visual inspection methods used by specialists
• select suitable testing methods
• interpret test results of the various components of concrete structures
• assess the useful life of concrete structures
• apply up-to-date knowledge for concrete repair and restoration to your projects
• evaluate concrete structures effectively
• increase durability of your concrete structures by understanding the causes of concrete failures
• employ relevant standards for your concrete restoration projects
• follow cost-effective strategies for concrete restoration
• decide whether or not the replacement of a concrete structural member can be avoided
• choose the right test for the right job

Description
The deterioration of concrete structures is a very serious problem, and there is currently a lack of guidelines and procedures for assessing, testing, classifying, and prioritizing preventive and corrective action to restore concrete structures.

In many cases, the evaluation of existing concrete structures is done by visual inspection. However, many defects are not evident either because they are physically concealed (as in underground components) or lie beneath surfaces (as in corrosion damage or cracking). Selecting appropriate and cost-effective rehabilitation measures is often hampered by limited information on the structural defects.

Engineers and other professionals need to keep abreast with the latest advances in diagnostic methods, materials, and techniques for the rehabilitation and upgrading of concrete structures. This course explains the mechanisms responsible for the deterioration of concrete structures, the methodology to inspect such concrete structures, and the materials and techniques that can be used for their protection, rehabilitation, and repair. Participants will learn how to identify the causes behind the degradation of concrete structures, how to assess the risks associated, and how to mitigate those risks using informed decision-making and sound repair and rehabilitation techniques.

Case studies and observations from real-world structures will enforce the learning process, and participants will have the opportunity to share cases they have encountered in their professional practice.
