Purpose and Background

This webinar include a discussion of the many types of concrete deterioration methods of investigating concrete deterioration and methods of repairing deteriorated concrete structures in addition this webinar will include a discussion of methods of completing a successful deteriorated concrete assessment the webinar will also discuss petrographic analysis of deteriorated concrete and the method of reinforcing corrosion on deteriorated concrete at the conclusion of the webinar 3 deteriorated concrete project examples will be discussed.

Benefits and Learning Outcomes

Upon completion of this course, you will be able to:

1. Become familiar with the steps involved with a successful deteriorated concrete investigation.
2. Understand types of concrete deterioration
3. Become familiar with the petrographic analysis of deteriorated concrete.
4. Become knowledgeable of the types of concrete deterioration that can be determined by petrographic analysis
5. Become familiar with the concrete deterioration associated with reinforcing corrosion.
6. Become familiar with the types of typical concrete repair details.
7. Learn how all of the above learning outcomes were applied to three different deteriorated concrete structure investigation and repair projects.

Assessment of Learning Outcomes

Students' achievement of the learning outcomes will be assessed via a short post-assessment (true-false, multiple choice and fill in the blank questions).
