Standard Test Methods for Integrity Testing of Concrete Deep Foundations by Thermal Methods

Importancia y uso:

5.1 Temperature measurements taken from a thermal probe lowered into access ducts in the deep foundation element, or from embedded thermal sensors distributed along the length, or from embedded fiber optic cables can indicate the homogeneity and integrity of concrete both inside and outside the reinforcing cage, as well as placement of the cage relative to the center of the curing concrete.5, 6

Note 2: The quality of the result produced by this standard is dependent on the competence of the personnel performing it and the suitability of the equipment and facility used. Agencies that meet the criteria of Practice D3740 are generally considered capable of competent and objective testing/sampling/inspection. Reliable results depend on many factors; Practice D3740 provides a means of evaluating some, but not all, of those factors.

Note 3: If anomalies are detected, then further evaluation may be warranted. Any interpretation is qualitative and possibly relative to the particular deep foundation element material, construction characteristics of the tested structure, and the apparatus used. Interpretation therefore should incorporate proper engineering judgment and experience.
