COURS.

APERÇU

After participating in the seminar you will be able to do the following:

• Diagnose durability problems
• Apply non-destructive testing methods
• Design surface repair strategies
• Identify the best materials for repair
• Achieve cost effectiveness in restoration projects

Description:
Despite the costly and tragic failures of some North American concrete structures, there is currently a lack of guidelines and procedures for assessing, testing, classifying, and prioritizing preventive and corrective action for these structures. This course focuses on training participants to properly diagnose the root causes of damage in concrete structures, to develop effective repair strategies, and select the right repair materials.

Case studies and observations of existing structures will enhance the learning process, and participants will have the opportunity to discuss real cases that they have been exposed to in their professional practice.

Course Outline:

• Mechanisms of premature damage in concrete structures
• Non-destructive testing methods for hidden defects
• Surface repair methods for concrete structures.
• Epoxy injection of cracks
• Repairing and strengthening using fibre-reinforced polymers
• Condition survey of concrete structures
• Failure analysis and forensic engineering

Who Should Attend:
Designers, Construction & Structural Engineers • Project Managers • Technicians & Technologists • Engineers in Training • Construction Inspectors • Inspection Officials • Facility Managers • Architects 

Horaire : 9:30 AM - 5:30 PM EDT

FORMATEUR

Moncef L. Nehdi, FCAE, FEIC, FACI, FCSCE, FAAIA

Dr. Moncef L. Nehdi, Ph.D., P. Eng.

Dr. Nehdi received his BASc from Laval University, MASc from Sherbrooke University, and PhD from the University of British Columbia, all in civil engineering. Prior to joining McMaster University, he was a professor in the Department of Civil and Environmental Engineering at Western University from 1999 to 2021. His industrial experience includes serving as Technical Manager for three different companies: Imasco Minerals Inc., Materials Technology Laboratories, and BCS. He also served as Associate Director for Environmental Research Western. 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, and was co-chair of the Infrastructure Division of NSERC’s Discovery Grant Committee 1509. During sabbatical leaves, he was visiting research professor at Qatar University, inaugural chair of urban planning at Alhosn University in Bau-Dhabi, the United Arab Emirates, and worked in Saudi Arabia on the world’s next tallest building, the world’s third tallest building, the world’s largest airport, the world’s most venerated pedestrian bridge, and the world’s deepest and second largest water treatment plant
