Abstract:
In-place tests have been developed to facilitate monitoring in-place strength development of concrete. Statistical procedures have also been developed for a reliable estimate of in-place compressive strength from the results of in-place tests (ACI 228.1R). However, rigorous statistical computations for obtaining the strength relationship and estimating the in-place characteristic strength are complex, time consuming and prone to error. A prototype computer system named "In-Place Concrete Test Analysis and Correlation" (INPLACE) has been developed to assist in implementing an in-place testing program. This paper briefly introduces the framework of the INPLACE system and summarizes how it operates.
