1. A logger capable of being positioned on or within a concrete mass, comprising:

  • one or more temperature sensors to measure physical properties of the concrete mass and to generate sensor data associated with the temperature of the concrete mass;

    a memory device that receives and stores strength-maturity correlation data formed by varying the proportions of water-to-cementitious ratio, air content, and maturity data in a plurality of calibration batches and then obtaining strength measurements while breaking the calibration batches and also receiving and storing the relative proportions of water, cement, and air content;

    a microprocessor which accesses the strength-maturity correlation data and receives the sensor data and calculates maturity data and mechanical strength data based on the strength-maturity correlation data and the relative proportions of the water, cement, and air content; and

    an encasement enclosing the memory device and microprocessor.
