As of 2025, this is still the 2010 edition. While ACI reaffirmed it (meaning the technical content is still sound), some references to equipment or data logging feel dated. You will not find modern discussion of digital image correlation or non-destructive testing (NDT) integration here.
ACI 214.4R-10 is a technical guide outlining standardized procedures for extracting concrete cores and interpreting compressive strength, crucial for assessing in-place structural capacity. It addresses critical variations in consolidation and curing, providing correction factors for L/D ratios and moisture to determine equivalent specified strength.

This is where enters the conversation. It provides the authoritative guide for core testing . Drilling cores from the actual structure is the most definitive way to assess in-place strength. But interpreting these results is not as simple as reading a number off a machine. ACI 214.4R-10 provides the statistical and procedural roadmap to interpret these results fairly and accurately.
