Description :
This training course is the first edition of a new complementary subject covered by the ACI local chapter. Durability of concrete is a quite large subject which include durability planning, proactive or reactive management of potential major pathologies, durability design methods, diagnosis and repair interventions. This training course is 16 hours divided into two days of 8h and include theory sections along with case studies to be solved in teams by the participants on the mentioned above subjects.
Day1 :
- Definitions and Context
- Definitions and context
- Normative requirements – durability specifications in construction projects
- Responsibilities of project stakeholders
- Owner / Client
- Project Manager
- Designer
- Contractor
- Suppliers / Concrete producers
- Major Pathologies
- Reference works/publications
- Shrinkage and cracking
- Corrosion of reinforcement
- Alkali-aggregate reaction (AAR and ASR)
- Freeze-thaw (all types)
- Spalling due to freeze/thaw and de-icing salts
- External sulfate attack (ESA)
- Internal sulfate attack (ISA or RSI) including
- Delayed ettringite formation (DEF or FED)
- Acid attack
Day 2 :
- Durability Design Methodologies
- Objective - Concept
- Different approaches to durability design
- Service life assessment - the different stages
- Service life and limit states
- Definition of exposure zones and conditions
- Identification of deterioration mechanisms
- Modeling of deterioration mechanisms
- Prevention of deterioration
- Testing methods to determine inputs
- Quality control during construction phase - testing methods for inputs
- Maintenance plan (Chapter 4)
- Examples of service life analyses in infrastructure projects
- Diagnosis and Interventions
- Prevention of premature damage and deterioration (Chapter 2)
- Maintenance and upkeep of the structure for a specified service life
- Inspection
- Expert evaluation of reinforced or prestressed concrete structure – assessment of residual service life
- Diagnosis
- Intervention
Notes :
- The “Troubleshooting” training course by the ACI is recommended, but not mandatory, before enrolling in this course. It is implicit that participants have a basic to intermediate understanding of concrete to fully benefit from the course content.
- The course covers concepts and definitions commonly encountered in large construction projects, major concrete pathologies, potential solutions to resolve them, durability design methodologies aligned with project objectives, and diagnosis and interventions when the expected durability of a project is not achieved. It also includes presentations of several testing methods for fresh and hardened concrete to accurately characterize the concrete planned for a project based on durability objectives.
- A certificate of completion, including the number of hours attended, will be provided at the end of the course (especially for members of the OIQ).
- A minimum of 15 participants is required for the course to take place, and a maximum of 35 participants per class will be allowed to ensure good interaction with the instructors.”
