ASTM D8173-23

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.

Geosynthetic Cementitious Composite Mats
This standard is issued under the fixed designation D8173; 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 guide covers directions for the installation of a geosynthetic cementitious composite mat (GCCM) materials under field
conditions typically present in erosion control, hydraulic structure armoring and protection, and protection applications. This guide
also covers directions for the installation of a special category of GCCMs known as geosynthetic cementitious composite barrier
(GCCB) materials, under field conditions typically present in geotechnical or civil engineering applications, with the purpose of
reducing or preventing the flow of fluid through the construction.
1.2 The values in SI units are to be regarded as the standard. Values in inch-pound units are in parentheses for information.
1.3 This guide contains general guidelines. It is not intended to replace project-specific installation requirements. In the event of
a conflict between the two, the requirements of the project specifications will supersede the requirements of this guide.
1.4 This is not an all-inclusive guide, and some projects will be beyond the scope of this guide.
1.5 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, health, and environmental practices and determine the applicability of
regulatory limitations prior to use.
1.6 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.
