ASTM C884/C884M-23

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: C884/C884M − 16 C884/C884M − 23
Standard Test Method for
Thermal Compatibility Between Concrete and an Epoxy-
Resin Overlay
This standard is issued under the fixed designation C884/C884M; 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 which epoxy-resin formulations are subject to debonding when used as overlays
for concrete when the combination of the two is subjected to temperature changes that may be met in the field.
1.2 Units—The values stated in either SI units 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 specification.
1.3 The text of this standard refers to notes and footnotes that provide explanatory material. 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 healthsafety, health, and environmental practices and determine
the applicability of regulatory limitations prior to use.A specific hazard statement is given in Section 8. . (Warning—Fresh
hydraulic cementitious mixtures are caustic and may cause chemical burns to exposed 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 Definitions:
3.1.1 For definitions of terms used in this test method, refer to Terminology C125.
4. Summary of Test Method
4.1 A layer of epoxy-sand mortar is applied to a slab of dried concrete. After the epoxy has cured, the sample is subjected to five
cycles of temperature change between 23°C [73.5°F] and –21°C [–6°F].23 °C [73.5 °F] and –21 °C [–6 °F]. Cracks near the bond
line between the concrete and the epoxy mortar constitute failure of the test.
5. Significance and Use
5.1 This test method applies to materials used in making epoxy-mortar overlays for concrete pavement. If debonding occurs
between the overlay and the pavement, the material is unsuitable.
5.2 This test method evaluates the ability of an overlay to remain bonded to a concrete substrate during repeated thermal cycling
in air over a significant temperature range and is not intended to duplicate temperature fluctuations in the field.
6. Apparatus
6.1 Molds, in conformance with Test Method C672/C672M.
6.2 Freezer, in conformance with Test Method C672/C672M, except that the temperature of the freezer shall be –21 6 2°C [–6
6 3°F].be –21 °C 6 2 °C [–6 °F 6 3 °F].
6.3 Retaining strips, to retain the epoxy-mortar overlay. Pieces of wood or steel that can be attached to the 300 by 300300 mm
by 300 mm by 75 mm [12 by 12 by 3-in.][12 in. by 12 in. by 3 in.] concrete block so as to enclose completely the top surface of
the block and rise above it a uniform distance of 15 mm [0.5 in.].
