Description

ASTM C1922-23

Active Standard: Standard Test Method for Water Retention of Hydraulic Cement-Based Mortars and Plasters by Way of Water Loss

ASTM C1922

Scope

1.1 This test method provides for the determination of water retention of hydraulic cement based mortars and plasters. Water Retention is directly measured through the absorption of water from the mortar by the substrate. Various substrates may be chosen by the user based on the intended use of the tested mortar. This test method defines such substrates. Comparisons can be made between different mortars on the same substrate or the same mortar on different substrates.

1.2 This test method provides a water retention value via direct water loss, while Test Method C1506 provides a water retention value via mortar flow.

1.3 Units—The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. When combined standards are cited, the selection of the measurement systems is at the user’s discretion subject to the requirements of the referenced standard.

1.4 The text of this test method references 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.

1.5 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. See the Safety Data Sheet for safety information regarding the materials being tested.

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.
