Please note that it is a requirement for all attendees to sign a "Confidentiality Agreement" prior to receiving the course notes for this online offering.
After participating in the course, 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 the 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 proper test for the right job
The deterioration of concrete structures is a severe problem. There is 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 structural defects.
Engineers and other professionals must keep abreast with the latest advances in diagnostic methods, materials, and techniques for rehabilitating and upgrading 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 used for their protection, rehabilitation, and repair. Participants will learn how to identify the causes behind the degradation of concrete structures, assess the associated risks, and mitigate those risks using informed decision-making and good 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.
Who Should Attend
Construction and structural engineers, designers, owners, consulting engineers, architects, technicians and technologists, contractors, facility managers, construction inspectors, inspection agency officials or building managers with responsibility for maintenance or rehabilitation of both public and private concrete structures, manufacturers and suppliers of specialty products, and anyone who needs to learn about concrete testing methods.
Time: 9:30 AM - 5:30 PM Eastern Time

Concluding Remarks and Final Adjournment
Professor and Chair
Moncef received his BASc from Laval University, MASc from Sherbrooke University, and Ph.D. from the University of British Columbia, all in civil engineering. Currently professor and chair of the Department of Civil Engineering at McMaster University. He was previously the professor of civil and environmental Engineering at Western University, where he also served as associate director for Environmental Research Western.
His industrial experience includes serving as technical manager for three different companies. He was licensed as a professional engineer in British Columbia in 1998 and in Ontario in 1999. He is past chair of the ACI committee 555 on recycled materials, chair of the CSCE sub-committee on cement and concrete, vice-chair of the CSCE Mechanics Division, depute chair of the RILEM committee on concrete data science, and was co-chair of the Infrastructure Division of NSERC’s Discovery Grant Committee 1509.
He has provided consulting services for some world landmark projects including the world's tallest buildings, the world’s largest airport, the world’s most venerated pedestrian bridge, and the world’s deepest and second-largest water treatment plant.
