Overview

Please note, This instructor-led course has specific dates and times:
This course is held online over 3 days on the following schedule (All times in Eastern Time Zone):

Day 1: 10 am to 6 pm Eastern (Will include the usual breaks)
Day 2: 10 am to 6 pm Eastern (Will include the usual breaks)
Day 3: 10 am to 1:30 pm Eastern (Will include the usual breaks)

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 and Structural Engineers • Project Managers • Technicians and Technologists • Engineers in Training • Construction Inspectors • Inspection Officials • Facility Managers • Architects

Time: 10:00 AM - 6:00 PM Eastern Time

Instructor

Moncef L. Nehdi, PhD, P.Eng., FCAE, FEIC, FACI, FCSCE, FAAIA


Professor and Chair

Moncef received his BASc from Laval University, MASc from Sherbrooke University, and PhD from the University of British Columbia, all in civil engineering. Currently professor and chair of the department of civil engineering at McMaster University, he previously was 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 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 world's tallest buildings, world’s largest airport, world’s most venerated pedestrian bridge, and world’s deepest and second largest water treatment plant.
