Influence of Datum Temperature and Activation Energy on Maturity Strength Predictions
The influence of datum temperature and activation energy on the accuracy of strength prediction via the maturity method was investigated by an iterative search method to find values of those parameters that minimized the difference between predicted and measured compressive strengths. Values of datum temperature and activation energy producing minimum error ranged from close agreement with ASTM C1074 recommendations to being unexpectedly and significantly higher or lower than values conventionally assumed. Once minimum error was established, no intrinsic superiority in accuracy of strength prediction by either Nurse-Saul or Freiesleben Hansen-Pederson maturity methods was observed. The method proposed, or other similar approaches to systematically increment input parameters to achieve minimum errors, can provide an alternative method for finding effective values of datum temperature and activation energy for a specific concrete and environment.
