Abstract
The method and apparatus for the non-destructive evaluation of a concrete mass uses the maturity method for evaluating the strength and durability of the concrete mass. The apparatus employs sensors which are implanted in the concrete along with a microprocessor and non-volatile RAM or EEPROM. A microcomputer is used periodically to up load the RAM and to make an evaluation of the concrete mass.

A method for non-destructive strength evaluation of a concrete mass comprising:
- (a) implanting an internal temperature sensor in said concrete mass before said concrete mass has hardened;
- (b) attaching a reference temperature sensor externally to said concrete mass before said concrete mass has hardened;
- (c) attaching a microprocessor to said internal temperature sensor and to said reference temperature sensor such that signals from said internal temperature sensor and said reference temperature sensor are transmitted to said microprocessor and recorded by said microprocessor, thereby obtaining a temperature profile of said concrete mass;
- and
- (d) tapping said microprocessor with a computer thereby down loading said microprocessor into said computer whereby said computer evaluates the strength of said concrete mass.
