ASTM C1064/C1064M-08

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

Standard Test Method for

Temperature of Freshly Mixed Hydraulic-Cement Concrete
This standard is issued under the fixed designation C1064/C1064M; the number immediately following the designation indicates the
year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last
reapproval. A superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
This standard has been approved for use by agencies of the Department of Defense.
1. Scope*
1.1 This test method covers the determination of temperature of freshly mixed hydraulic-cement concrete.
1.2 The values stated in inch-pound either SI or SIinch-pound units are to be regarded separately as standard. Within the text,
SI units are shown in brackets. The values stated in each system aremay not be exact equivalents; therefore, each system shall be
used independently of the other. Combining values from the two systems may result in non-conformance with the specification.
standard.
1.3 The text of this standard references notes and footnotes that provide explanatory information. These notes and footnotes
(excluding those in tables and figures) shall not be considered as requirements of this standard.
1.4 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. (Warning—Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and

tissue upon prolonged exposure. )

3. Significance and Use
3.1This test method provides a means for measuring the temperature of freshly mixed concrete. It may be used to verify
conformance to a specified requirement for temperature of concrete.
3.1 This test method provides a means for measuring the temperature of freshly mixed concrete. The measured temperature
represents the temperature at the time of testing and may not be an indication of the temperature of the freshly mixed concrete at
a later time. It may be used to verify conformance to a specified requirement for temperature of concrete.
3.2 Concrete containing aggregate of a nominal maximum size greater than 3 in. [75 mm] may require up to 20 min for the
4
transfer of heat from aggregate to mortar. (See ACI Committee 207.1R Report. )
4. Apparatus
4.1 Container, shall be large enough to provide at least 3 in. [75 mm] of concrete in all directions around the sensor of the
temperature measuring device; concrete cover must also be at least three times the nominal maximum size of the coarse aggregate.
4.2 Temperature Measuring Device, shall be capable of accurately measuring the temperature of the freshly mixed concrete to
61°F[6 0.5 °C] throughout a range of 30° to 120 °F [0° to 50 °C]. The design of the temperature measuring device shall be such
that it allows 3 in. [75 mm] or more immersion during operation.
4.3 Partial immersion liquid-in-glass thermometers (and possibly other types) shall have a permanent mark to which the device
must be immersed without applying a correction factor.
