Volume Changes of Concrete Webinar

PCA Webinar
Date: Thursday, October 15, 2009
Time: 12 - 1 pm CDT

Volume Changes of Concrete

Apparatus for measuring length of mortar bars

The webinar will cover the variables that affect volume changes in concrete. If concrete were free of any restraints to deform, normal volume changes would be of little consequence; but since concrete in service is usually restrained by foundations, subgrades, reinforcement, or connecting members, significant stresses can develop. Cracks can develop because concrete is relatively weak in tension but quite strong in compression.

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

1. Define the variables that affect volume changes in concrete.
2. Understand the nature of volume changes in concrete for planning or analyzing concrete work.
3. Learn how to control the variables that affect volume changes so they can minimize high stresses and cracking.

Verified participants in this webinar will be awarded 0.1 CEUs (usable for 1.0 PDH in most places) sent via email after submitting an evaluation.

Registration for this webinar includes a downloadable (PDF) entitled Volume Changes of Concrete, Chapter 15 of PCA’s publication: Design and Control of Concrete, EB001.
