(Specification)Standard Specification for Preblended Dry Mortar Mix for Unit Masonry
Standard Specification for Preblended Dry Mortar Mix for Unit Masonry
ABSTRACT
This specification covers unit masonry mortars whose material and design requirements are governed by a referenced ASTM document stated herein, but are preblended dry in a factory instead of produced from individual raw materials delivered to the job-site. Because field sampling, testing, directly comparable test results, packaging, and traceability of ingredients of preblended dry mortar mix differ from job site mixed mortars, this specification particularly addresses these issues, along with the tight control of ingredient ratios possible with preblended dry mortars.
SCOPE
1.1 This specification covers masonry mortars whose materials and design requirements are governed by Specification C270 but are preblended dry in a factory instead of produced from individual raw materials delivered to the job-site.
1.2 The field-sampling, testing, directly comparable test results, packaging, and the traceability of ingredients of preblended dry mortar mix differ from job site mixed mortars and this standard specifically addresses these issues. The tight control of ingredient ratios possible with preblended dry mortar is also covered.
1.3 The text of this specification refers to notes and footnotes, which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered the requirements of the standard.
1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
1.5 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 and health practices and determine the applicability of regulatory limitations prior to use. Warning—Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure.
