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. The property specification of this standard applies to mortar mixed to a specific flow in the laboratory.
This standard has been approved for use by agencies of the U. Thank you for interesting in our services. The property specification requires that the mortar exhibit certain characteristics when tested under laboratory conditions. Mortar for such masonry should be selected with due caution. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
Four types of mortar are covered in each of two alternative specifications: This specification provides the basis for five different mortar types Type K is listed in section X3 of the appendix depending on the strength of mortar needed for an application. First, the mortar type must be determined based on the strength required for the application.
For cement-lime mortars, the proportion specification will indicate the volume of portland cement followed by the volume of hydrated lime and finally the volume of sand. 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.

When neither the proportion or property specifications are specified, the proportion specifications govern. Zstm Item s – proposed revisions of this standard. Portland cement-lime mortars should be specified by either the property or the proportion specification but not both. This specification does not cover the determination of mortar strengths through field testing.
