The objective of this course is to introduce the latest research and design information on using shrinkage-compensating concrete for various structural applications to avoid drying shrinkage cracking. Different types of shrinkage-compensating concrete will be discussed: a. how it is produced in design mixes and b. how shrinkage-compensating cement affects early strength properties in comparison to ordinary Portland cement design mixes.

The contents of this course include four recorded presentations from the ACI 2021 Fall Virtual Convention.
1. Novel Structural Repair Using Shrinkage Compensating Concrete, by Royce Floyd, The University of Oklahoma
2. Crack-Free Bridge Decks and Water Tanks, by Chris Ramseyer, University of Oklahoma
3. Development of a Novel Shrinkage-Compensating Cement, by Eric Bescher, University of California, Los Angeles
4. Shrinkage-Compensating and Nonshrink Labels on Proprietary Repair Materials – What Do They Mean? by Benoit Bissonnette, Laval University

1. Discuss production and properties of shrinkage-compensating concrete in a concrete mixture in relationship and comparison with ordinary Portland cement concrete.
2. Discuss the latest research concerning shrinkage-compensating concrete.
3. Expand the use and understanding of shrinkage-compensating concrete, including some repair applications.
4. Explain differences in specifying shrinkage-compensating cement in contract documents.
