Utilization of Maturity Meters for Concrete Quality Assurance Final rept

摘要

The maturity method is a non-destructive technique used to estimate in-place strength of concrete. The technique is relatively new and no good knowledgebase is available in most organizations about its field implementation. The Florida Department of Transportation (FDOT) is currently considering specifications for using the maturity method as a quality assurance (QA) tool. The objective of this research was to investigate the effects on concrete maturity index and strength due to type and location of maturity sensors, and on developing specific guidelines.
