(Specification)Standard Specification for Grout for Masonry
Standard Specification for Grout for Masonry
ABSTRACT
This specification covers two types of grout, fine and coarse grout, for use in the construction of masonry structures. Grout is specified by proportions or strength requirements. Materials used as ingredients in grout shall conform to the requirements specified such as: cementitious materials; blended cements; quicklime; hydrated lime; coal fly ash or raw calcine natural pozzolan; granulated blast furnace slag; air-entraining admixtures; aggregates; water; pumping aids; antifreeze compounds; and storage of materials. Fine grout shall be manufactured with fine aggregates. Coarse grout shall be manufactured with a combination of coarse and fine aggregates. Proportions of ingredients shall be determined by grout proportion requirements and by the specified compressive strength. Materials for grout shall be measured in such a way that the required proportions of the grout materials are controlled and accurately measured. Grout shall be produced using one of the following procedures: grout materials mixed with water at the job site and ready-mixed grout transported to the job site.
SCOPE
1.1 This specification covers two types of grout, fine and coarse grout, for use in the construction of masonry structures. Each type (fine and coarse) is further classified as conventional grout (requiring mechanical consolidation by puddling or vibration when placed) and self-consolidating grout (not requiring mechanical consolidation when placed). Conventional grout is specified by (1) proportions or (2) strength requirements. Self-consolidating grout is specified by strength requirements.
1.2 The text of this specification 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 specification.
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.4 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.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
