A completed revision of ACI 228.1R: Report on Methods for Estimating In-Place Concrete Strength was published in January 2019 as 228.1R-19. This session will be of interest to practicing engineers engaged in structural assessment, those engaged in QA/QC on new construction, and educators who teach advanced courses in concrete repair, forensics, and nondestructive testing. Attendees will learn about standardized test methods used to estimate in place strength, including the underlying principles, advantages, and limitations of the tests. They will also learn about how to properly interpret the results of in place tests, the statistical significance of test results, and plan an in-place testing program. The session will also incorporate several case study presentations on successful implementation of in place testing.

The contents of this course include four recorded presentations from the ACI 2019 Fall Convention:
• Introduction to the Revised ACI 228.1R-19 by John Popovics, University of Illinois at Urbana-Champaign
• Rebound Number, Penetration Resistance, Pullout, Pull-off, and Maturity Testing Methods by Christopher Ferraro, University of Florida
• UPV, Cast-in-place Cylinders, and Combined Methods by John Popovics, University of Illinois at Urbana-Champaign
• Statistical Considerations: More Than a Line by Nicholas Carino

1. Describe ASTM standard test methods that can be used to estimate in-place concrete strength and select appropriate tests for applications to new and existing structures.
2. Discuss advantages and limitations of ASTM standard test methods that can be used to estimate in-place concrete strength.
3. Interpret and discuss the statistical significance of in-place test results.
4. Discuss factors to consider when planning in-place testing programs for new and existing structures.
