Description

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 of new constructed concrete structures or existing concrete structures, those engaged in QA/QC on new construction or rehabilitation of existing concrete 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.

Learning Objectives

1. Discuss factors to consider when planning in-place testing programs for new and existing structures, and guidance to ensure the sample size is significant,

2. Describe how nondestructive testing (NDT) methods were employed singly or in combination for in-place strength estimation on several real-world projects.

3. Give examples of the benefits and limitations of maturity testing in new construction and discuss key considerations for the successful implementation of a maturity testing program.

4. Describe the role of uncertainty in estimating in-place concrete strength using NDT methods, in the context of spatial variation within a structure and of quality control of large numbers of CMUs or precast concrete products.
