Abstract
A system for providing reliable, unalterable mechanical data associated with the mechanical properties of a concrete mass. The system includes a logger, a second memory device and an outbound data transfer device. The logger is provided with one or more sensors, a microprocessor and a first memory device. The one or more sensors measure physical properties of the concrete mass and generate data associated with the physical properties. The microprocessor receives the data from the sensor and calculates maturity data and mechanical strength data. The first memory device stores the mechanical strength data within the concrete mass in an unalterable form. The second memory device is located outside the concrete mass. The outbound data transfer device transfers the mechanical strength data from the first memory device to the second memory device.
