Abstract
Method and system for controlling and monitoring the quality of concrete based on the concrete's maturity. Various embodiments of the present invention are discussed. First, Enhanced Maturity involves a maturity calibration method to account for the water-to-cementitious-materials ratio, air content, and gross unit weight of the concrete. Second, Moisture-Loss Maturity is a method for determining the appropriate time to terminate moisture-loss protection of concrete and concrete structures. Third, Improved Maturity is a method and system for determining the strength of curing concrete using improved maturity calculations. Fourth, SPC Maturity is a method that beneficially couples maturity measurements and calculations with Statistical Process Control (SPC) methods to enable rapid recognition of changes to the concrete mix and/or incompatibilities between the various components of the concrete mix. Fifth, Loggers, Readers, and Software represent the preferred embodiment for automating and simplifying the implementations of the aforementioned methods.
