    Abstract - (Show below) - (Hide below)

    CONTAINED IN VOL. 04.09, 2015 Specifies procedures for measuring the temperature profile within a deep foundation element constructed using cast-in-place concrete, such as bored piles, drilled shafts, augered piles, diaphragm walls, barrettes, and dams, and alike.

    Scope - (Show below) - (Hide below)

    1.1These test methods provide procedures for measuring the temperature profile within a deep foundation element constructed using cast-in-place concrete, such as bored piles, drilled shafts, augered piles, diaphragm walls, barrettes, and dams, and alike. The thermal profile induced by the curing concrete can be used to evaluate the homogeneity and integrity of the concrete mass within the deep foundation element.

    1.2Two alternative procedures are provided:

    1.2.1Method A uses a thermal probe lowered into access ducts installed in the deep foundation element during construction.

    1.2.2Method B uses multiple embedded thermal sensors attached to the reinforcing cage installed in the deep foundation element during construction.

    1.3All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D6026, unless superseded by this standard.

    1.3.1The procedures used to specify how data are collected/recorded and calculated in this standard are regarded as the industry standard. In addition, they are representative of the significant digits that should generally be retained. The procedures used do not consider material variation, purpose for obtaining the data, special purpose studies, or any considerations for the user’s objectives; and it is common practice to increase or reduce significant digits of reported data to commensurate with these considerations. It is beyond the scope of this standard to consider significant digits used in analysis methods for engineering design.

    1.4This standard provides minimum requirements for thermal profiling of concrete deep foundation elements. Plans, specifications, and/or provisions prepared by a qualified engineer, and approved by the agency requiring the test, may provide additional requirements and procedures as needed to satisfy the objectives of a particular test program.

    1.5The text of this standard references notes and footnotes, which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.

    1.6Units—The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

    Note 1:ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility.

    1.7Limitations—Proper installation of the access ducts or thermal sensors is advised for effective testing and interpretation. If a flaw is detected, then the method does not give the exact type of flaw (for example, inclusion, bulge, honeycombing, lack of cement particles, and alike.) but rather only that a flaw exists. The method is limited primarily to testing the concrete during the early curing process.

    1.8This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
