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.

Claims

1. A system for providing reliable, unalterable mechanical data associated with the mechanical properties of a concrete mass, comprising:

a logger in the concrete mass, comprising;

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

a microprocessor that receives the data from the sensor and calculates maturity data and mechanical strength data; and

a first memory device for storing the mechanical strength data within the concrete mass in an unalterable form;

a second memory device located outside the concrete mass; and

an outbound data transfer device to transfer the mechanical strength data from the first memory device to the second memory device.

2. The system of claim 1 wherein the physical properties measured by the one or more sensors are selected from a group of physical properties consisting of temperature, moisture, relative humidity, electrical conductivity, thermal conductivity, alkalinity, oxidation-reduction potential, and sonic velocity.

3. The system of claim 1 further comprising a time-keeping device to track the time between the measurements of the physical properties.

4. The system of claim 3 wherein the maturity data and mechanical strength data are calculated for each measurement.

5. The system of claim 1 wherein strength-maturity calibration data are stored within the first memory device.

6. The system of claim 5 wherein the microprocessor calculates the mechanical strength data from the maturity data and the strength-maturity calibration data.

7. The system of claim 6 wherein the first memory device stores the calculated mechanical strength data.

8. A system for providing reliable, unalterable mechanical data associated with the mechanical properties of a concrete mass, comprising:

a logger in the concrete mass, comprising;

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

a microprocessor that receives the data from the sensor and calculates maturity data and mechanical strength data; and

a first memory device for storing the mechanical strength data within the concrete mass in an unalterable form;

a reader located outside the concrete mass, the reader transferring the mechanical strength data from the first memory device to the reader.

9. The system of claim 8 wherein the physical properties measured by the one or more sensors are selected from a group of physical properties consisting of temperature, moisture, relative humidity, electrical conductivity, thermal conductivity, alkalinity, oxidation-reduction potential, and sonic velocity.

10. The system of claim 8 further comprising a time-keeping device to track the time between the measurements of the physical properties.

11. The system of claim 10 wherein the maturity data and mechanical strength data are calculated for each measurement.

12. The system of claim 8 wherein strength-maturity calibration data are stored within the first memory device.
