Air-Entrained Concrete
One
of the greatest advances in concrete technology was the development of
air-entrained concrete in the 1930s. Today air entrainment is recommended
for nearly all concretes, principally to improve freeze-thaw resistance
when exposed to water and deicing chemicals. However, there are other
important benefits of entrained air in both freshly mixed and hardened
concrete. This webinar will discuss air-entrained concrete.
At the end of this course, participants will have the ability to:
| • recognize the properties of air-entrained concrete |
| • identify recommended air contents and tests |
| • discuss the factors that affect air content |
Upon completion of
the webinar, registered participants will be emailed a copy of the presentation
slides, a certificate for 0.1 CEU credit, and a PDF of “Air-Entrained
Concrete”, Chapter 8 of PCA’s Design and Control of Concrete
Mixtures, 14th edition, EB001
The cost of this one-hour
Webinar is $60.
$30 for PCA members; government officials (.gov); students and educators(.edu).
