(Specification)Standard Specification for Aggregates for Masonry Grout
Standard Specification for Aggregates for Masonry Grout
ABSTRACT
This specification covers aggregates used for masonry grout. Aggregates should consist of either natural or manufactured sand, used alone or in combination with course aggregates. The course aggregates should be made up of crushed stone, gravel, or processed air-cooled iron blast-furnace slag with suitable particle shapes. Both fine and course aggregates should meet the particle size requirements, contain the right amount of deleterious substances and pass the soundness tests. Fine aggregates should be free from injurious amounts of organic impurities.
SCOPE
1.1 This specification covers aggregate for use in grout for masonry.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 The text of this standard references notes and footnotes, which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of this standard.
1.4 The following precautionary caveat pertains only to the test methods portion, Section 9 of the standard. 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.
