Abstract
This specification covers three types of mortar cement for use where mortar for masonry is required. Mortar cements are classified as Type N, S, or M, according to the prescribed physical requirements. Mortar cement shall conform to the prescribed requirements such as fineness, autoclave expansion, time of setting, compressive strength, flexural bond strength, air content of mortar, and water retention. Test specimens shall undergo molding and storage before conducting the procedures in the required test methods.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
1. Scope
1.1 This specification covers three types of mortar cement for use where mortar for masonry is required.
1.2 The values stated in SI units are to be regarded as the standard. Values in SI units shall be obtained by measurement in SI units or by appropriate conversion, using the Rules for Conversion and Rounding given in IEEE/ASTM SI 10, of measurements made in other units.
1.3 The text of this standard refers to notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.
1.4 The following safety hazards caveat pertains only to Annex A1. 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.)
