Aggregates for Concrete

Although aggregates are considered primarily filler in concrete, the properties of aggregates greatly influence the properties and performance of both fresh and hardened concrete. In addition to the role aggregates have on the performance of concrete, they also play a large role in determining the economy of the mixture. This webinar will provide a comprehensive overview of aggregates for use in concrete.

At the end of this course users will be able to:

1. Describe, in general, the production process for aggregates used in concrete construction including; obtaining raw materials, crushing, screening, and washing.
2. Describe the primary effects aggregate properties have on fresh and hardened concrete properties.
3. Identify deleterious (harmful) materials that may occur in aggregates that can impact the quality of concrete.
4. List the applicable specifications associated with concrete aggregates.

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 “Aggregates for Concrete”, Chapter 5 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).
