About This Item
ASTM C1922 is the ASTM standard for evaluating water retention of hydraulic cement-based mortars and plasters by way of water loss. It provides a technical basis for measuring how well these mixtures hold water during handling and application, which can affect workability, placement, and finish quality. For users comparing products or verifying performance, this standard helps support consistent testing and more reliable material selection.
ASTM C1922 standard overview
ASTM C1922, titled Standard Test Method for Water Retention of Hydraulic Cement-Based Mortars and Plasters by Way of Water Loss, addresses a specific performance characteristic of cementitious mixtures. The method focuses on water loss as a practical indicator of water retention behavior in mortars and plasters. In product and quality-control settings, this kind of test method is commonly used to compare materials under consistent conditions and to support more objective evaluation of formulation performance.
Where is ASTM C1922 used?
This standard is commonly used wherever hydraulic cement-based mortars and plasters are tested, specified, or compared for performance. It is relevant in laboratory and quality-control workflows that evaluate mixture behavior before or during production use. ASTM C1922 may also be useful in procurement and product qualification processes when water retention is an important criterion for selecting cement-based materials for construction and finishing applications.
Practical importance of ASTM C1922
In practice, ASTM C1922 helps users assess whether a mortar or plaster retains water well enough to support consistent application and expected performance. That can matter for compliance, product development, incoming inspection, and lot-to-lot comparison. By using a recognized test method, manufacturers and specifiers can reduce ambiguity, improve repeatability, and make better decisions when evaluating cement-based materials against internal or contract requirements.
