CE-039 Freeze Thaw Resistance of Concrete with Marginal Air Content: 3 PDH
Description of the Freeze Thaw Resistance of Concrete with Marginal Air Content course
The Freeze Thaw Resistance of Concrete with Marginal Air Content online PDH course is a part of the Civil Engineering category of courses.
Freeze-thaw resistance is a key durability factor for concrete pavements. Recommendations for the air void system parameters are normally: 6 ± 1 percent total air, and spacing factor less than 0.20 millimeters. However, it was observed that some concretes that did not possess these commonly accepted thresholds presented good freeze-thaw resistance in laboratory studies.
This course discusses the freeze-thaw resistance of several “marginal” air void mixes, with two different types of air-entraining admixtures (AEA)—a Vinsol resin and a synthetic admixture. It incorporates using rapid cycles of freezing and thawing in plain water, in the absence of deicing salts.
This course is based on US Department of Transportation, Federal Highway Administration publication FHWA-HRT-06-117 “Freeze Thaw Resistance of Concrete with Marginal Air Content”.
This course is intended for civil engineers and other design and construction professionals interested in freeze thaw resistance of concrete with marginal air content.
At the end of the course, you will be able to:
- Understand concrete composition at chemical level and its microstructure
- Explain the use of Air-Entraining Admixtures
- Explain freeze-thaw damage mechanism
- Discuss role air voids play in resistance to freeze-thaw phenomenon
- Evaluate the water-cement (w/c) ratio influence on the freeze-thaw resistance of the mixes with Vinsol resin air-entraining admixture
- Compare the performance of the mixes with Vinsol resin and synthetic air-entraining admixtures

Length of the Course / Activity
This course is intended to be studied at self-pace and it should take on average of 3 hour to read and be able to comprehend the material to successfully past the online quiz.
To receive the certificate of completion for the above 3 PDH online course, you will need to take a 15-question multiple choice quiz based on the reference material supplied and pass with minimum score of 70%. There is no time limit for the quiz and it can be taken multiple times until a passing score of 70% is achieved.
Certificate of Completion
Once you achieve a passing score of 70% on the quiz you will receive and be able to print your Certificate of Completion as a record of your continuing education. PDH Star will keep a record of your certificate for the duration as required by your state of licensure. You will be able to log on to your account and view and print your past Certificate of Completion.
