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: C953 − 10 C953 − 17
Standard Test Method for
Time of Setting of Grouts for Preplaced-Aggregate Concrete
in the Laboratory
This standard is issued under the fixed designation C953; 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.
1. Scope*
1.1 This method covers the determination test of time of setting of hydraulic cement grout mixtures used in preplaced-aggregate
(PA) concrete using the vicatVicat apparatus.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 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
chemical burns to skin and tissue upon prolonged exposure.
1.4 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 Definitions:
3.1.1 For definitions of terms used in this test method, refer to Terminologies C125 and C219.
4. Summary of Method
4.1 The time of setting, initial and final, of a sample of fluid grout is determined using the Vicat apparatus.
5. Significance and Use
5.1 This test method determines the setting time of setting of grout mixed to the fluid consistency required for its use in PA
concrete.
5.2 The time of setting is also useful in determining the acceptability of components of grout that must be mixed to the fluid
consistency required for production of PA concrete.
This test method is under the jurisdiction of ASTM Committee C09 on Concrete and Concrete Aggregates and is the direct responsibility of Subcommittee C09.41 on
Hydraulic Cement Grouts.
