Mortar for such masonry should be selected with due caution. Any claim shall be deemed waived unless made in writing to us within 30 days from the earlier of the date it was or reasonably should have been discovered.

ASTM Standard C provides both a proportion specification and a property specification for each mortar type. Portland cement-lime mortars should be specified by either the property or the proportion specification aztm not both.

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. The property specification requires that the mortar exhibit certain characteristics when tested under laboratory conditions. Table 3 details the recipes required for atsm mortar type specified by proportion.

ASTM C – 14a Standard Specification for Mortar for Unit Masonry

The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. This specification covers mortars for use in the construction of non-reinforced and reinforced unit masonry structures. For example, a 1: Type O mortar is recommended for use where the masonry is unlikely to be frozen when saturated, or unlikely to be subjected to high winds or other significant lateral loads.

This specification does not cover the determination of mortar strengths through field testing. This abstract is a brief summary of the referenced standard.

The compressive strength values resulting from field tested mortars do not represent the compressive strength of mortar tested in the laboratory nor that of the mortar in the wall. For the purposes of determining volumes, ASTM C provides typical bulk densities for portland cement, hydrated lime and sand.

Our liability is expressly limited to replacement of defective goods. 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.

We need your help to maintenance this website. A number in parentheses indicates the year of last reapproval.
