Method and system for concrete quality control based on the concrete's maturity
First Claim
1. A logger capable of being positioned on or within a concrete mass, comprising:
- one or more sensors to measure physical properties of the concrete mass and to generate sensor data associated with the physical properties; and
a microprocessor receiving the sensor data and calculating maturity data and mechanical strength data based on maturity data, water-to-cementitious-materials ratio, and air content of the concrete mass.

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.
