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

1. Scope

The development of standards, and modifications thereof, for hydraulic cements, as well as other inorganic cements, their ingredients and combinations during manufacture, including specifications, test methods, classifications, guides, practices, and terminology. Investigation of the properties of hydraulic and other inorganic cements and promotion of improvement and reliability of testing of these materials. Provide joint sponsorship (with ASTM Committee C09 on Concrete and Concrete Aggregates) of the Cement and Concrete Reference Laboratory (CCRL), and liaison with international standards activities relating to cements.
The area of interest of the Committee comprises hydraulic and other inorganic cements and their ingredients, all characteristics thereof, and the means used to determine those characteristics.

Keywords

absorption, mortar; plaster; water retention

Rationale

This standard is needed to more directly measure the water retention capability of mortar materials. This new method is being designed to measure the actual water retention of the mix design in a simpler fashion by measuring the actual water loss of the mortar to substrates of varying absorption capabilities.

The title and scope are in draft form and are under development within this ASTM Committee.
