ASTM C1064/C1064M-17

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.
Designation: C1064/C1064M − 12 C1064/C1064M − 17
Standard Test Method for
1
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 U.S. 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 either SI or inch-pound units are to be regarded separately as standard. The values stated in each system
may 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 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 safety, health, and healthenvironmental practices and determine the
applicability of regulatory limitations prior to use. (Warning—Fresh hydraulic cementitious mixtures are caustic and may cause
2
chemical burns to skin and tissue upon prolonged exposure. )
1.5 This international standard was developed in accordance with internationally recognized principles on standardization
established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued
by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

3. Terminology
3.1 For definitions of the terms used in this test method, refer to Terminology C125.
4. Significance and Use
4.1 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.
4.2 Concrete containing aggregate of a nominal maximum size greater than 75 mm [3 in.] may require up to 20 min for the
4
transfer of heat from aggregate to mortar. (See ACI Committee 207.1R Report. )
5. Apparatus
5.1 Container, shall be large enough to provide at least 75 mm [3 in.] 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.
