ABSTRACT:
A method and system for controlling and monitoring the quality of concrete based on the concrete's maturity (which is a function of its time-temperature profile, or temperature history). Five different applications or embodiments of the present invention are discussed, namely, Enhanced Maturity, Moisture-Loss Maturity, Improved Maturity, SPC Maturity, Loggers, Readers, and Software. 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. Moisture-Loss Maturity is a method for determining the appropriate time to terminate moisture-loss protection of concrete and concrete structures. Improved Maturity is a method and system for determining the strength of curing concrete using improved maturity calculations. 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. Loggers, Readers, and Software represent the preferred embodiment for automating and simplifying the implementations of Enhanced Maturity, Moisture-Loss Maturity, Improved Maturity, and SPC Maturity.
