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.
