ABSTRACT:
A system that includes a logger to record mechanical data for a concrete mass and to transmit the mechanical data to a reader. The system includes sensors, a microprocessor and a first memory device embedded in the concrete mass for generating mechanical strength data for the concrete mass and storing that information in the first memory device. In one embodiment the mechanical data is encrypted to prevent third parties from downloading and reading the data. In another embodiment, the logger communicates with the reader through communication wires. In yet another embodiment, the logger transfers data files to the reader by radio frequency signals.
