| Significance and Use | ||||||||||||||||

4.1?This test method provides a laboratory procedure for determining the relative water absorption properties over time of mortars used for masonry construction. Because the specimens are made under laboratory conditions and do not take into account the effect of the masonry substrate or field mixing procedures, this method is not intended for field use. Data generated from this test method may be useful for determining the relative effectiveness of water repellent admixtures or the effect of other admixtures or mortar components on the water repellency of a mortar. However, use caution in interpreting the results. While the resistance of masonry to water penetration may be related to the water absorption of the mortar, it also depends on other factors, such as the workmanship, extent of bond, and the properties of the masonry units and mortar. Note 1:?This test method is specified in Specification
C1384 for demonstrating
compliance of mortar admixtures classified as Water Repellent. In
this compliance testing, the admixed mortar is compared to a
reference mortar made with the same mortar materials except that it
does not include the admixture. For quality control testing of
water repellent preblended dry mortar mixes, the reference mortar
is not typically available since the water repellent additive is
added during the manufacturing process prior to bagging the final
product. In these cases, the procedure in Annex A1 can be used to determine the
relative resistance of the mortar to absorption by capillary
uptake.

1.1?This test method covers a standardized laboratory procedure for determining the relative water absorption by capillary uptake (wicking) characteristics of masonry mortars. This test method is not applicable for determining the effectiveness of water repellent coatings. 1.2?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 the standard. 1.3?The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3.1?Inch-pound units are given in parentheses for temperature specification and are for information only. 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 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. |
