ASTM C1181/C1181M-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: C1181 − 00 (Reapproved 2012) C1181/C1181M − 17
Standard Test Methods for
Compressive Creep of Chemical-Resistant Polymer
Machinery Grouts
This standard is issued under the fixed designation C1181;C1181/C1181M; 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 Scope*
1.1 These test methods cover a quantitative, comparative test for compressive creep of chemical-resistant grouting materials
under a sustained load at a test temperature. Constant load is maintained using a bolt and spring washers. Measurements are made
at laboratory temperature after exposure periods at the selected test temperature.
1.2 Test Method A outlines the molding techniques for an unbonded test specimen. Test Method B covers the molding
techniques for a bonded test specimen.
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values given in
parentheses are mathematical conversions to SI units that are provided for information only and are not considered 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.
1.4 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.
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 Definitions—For definitions of terms used in these test methods, see Terminology C904.
4. Significance and Use
4.1 These test methods provide a means of measuring the total compressive deflection of chemical-resistant, machinery-grout
materials under a sustained load at the test temperature. Test stress and temperature can be selected to simulate anticipated use
conditions. For the purposes of these tests, creep is considered to be the compressive deflection in inches per inch, cm per cm
[inches per inch], which occurs after the initial loading of the specimen at laboratory temperature. The results do not necessarily
correlate for different specimen thicknesses. No correlation has been established to actual-use conditions.
5. Apparatus
5.1 Steel Loading Plates—Steel plates, as described, are used for loading the grout during the test. They may, also, be part of
the mold used to cast the grout specimen.
These test methods are under the jurisdiction of ASTM Committee C09 on Concrete and Concrete Aggregates and are the direct responsibility of Subcommittee C09.41
on Hydraulic Cement Grouts.
