C Specification for Admixtures for Masonry Mortars. Table 3 details the recipes required for each mortar type specified by proportion. Zstm are no warranties that extend beyond the description contained herein. These notes and footnotes excluding those in tables and figures shall not be considered as requirements of the standard. When neither the proportion or property specifications are specified, the proportion specifications govern. The compressive strength values resulting from field tested axtm do not represent the compressive strength of mortar tested in the laboratory nor that of the mortar in the wall.

First, the mortar type must be determined based on the strength required for the application. These notes and footnotes excluding those in tables and figures shall not be considered as requirements of the standard.

2c70 M mortar has the highest strength.

The property specification applies to mortar mixed to a specific flow in the laboratory. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

This specification does not cover the determination of mortar strengths through field testing. Link to Active This link will always route to the current Active version of the 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. Compliance to this specification is verified by confirming that the materials used are as specified, meet the requirements as given, and added to the mixer in the proper proportions as described.

When the property specification is used to qualify masonry mortars, the testing agency performing the test methods should be evaluated in accordance with Practice C Foundation wall, retaining wall, manholes, sewers, pavements, walks, and patios.

Type O mortar is recommended for use where the masonry c2700 unlikely to be frozen when saturated, or unlikely to be subjected to high winds or other significant lateral loads.

Four types of mortar are covered in each of two alternative specifications: 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.

Size px x x x x Adtm K mortar has the lowest compressive strength. Type N hydrated lime products must be laboratory tested to insure that they meet the property specification for the applicable mortar type in order to be acceptable for the proportion specifications. As seen in Table 4, compressive strength, water retention and air content tests are c2700 to be performed on the mortar mixed in the laboratory.

The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. For the purposes of determining volumes, ASTM Atm provides typical bulk densities for portland cement, hydrated lime and sand.

ASTM Asmt C provides both a proportion specification and a property specification for each mortar type. 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.

Work Item s – proposed revisions of this standard. Since jobsite water additions may not be the same as those in the laboratory, the properties of field mixed mortar cannot be compared to the property requirements of ASTM C We shall not be liable for incidental and consequential damages, directly or indirectly sustained, nor for any loss caused by application of these goods not in accordance with current printed instructions or for other than the intended use.

These densities are shown in Table 2. Portland cement-lime mortars should be specified by either the property or the proportion specification asym not both.

Current edition approved Dec. Work Item s – proposed revisions of this standard. This standard does not purport to address all of the safety concerns, if any, associated with its use.

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. Four types of mortar are covered in each of two alternative specifications: A number in parentheses indicates the year astn last reapproval.
