  • 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.

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.

Moncef L. Nehdi, P.Eng., Professor, FACI

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
