ASTM C1329

Full Name

ASTM C1329 – Standard Specification for Mortar Cement

Scope

ASTM C1329 defines the requirements for three types of mortar cement used in masonry construction. Mortar cement is a pre-blended material containing Portland or blended hydraulic cement, plasticizing materials (like limestone or lime), and other ingredients to enhance specific properties.

The scope of ASTM C1329 includes:

  • Types of mortar cement – it covers three types:
    1. Type N: for general use in exposed and interior masonry above grade.
    2. Type S: for use where high bond and compressive strengths are desired.
    3. Type M: for use in masonry below grade and in contact with earth.
  • Physical requirements: it specifies minimum requirements for compressive strength, bond strength, water retention, and air content for each type of mortar cement. These properties are essential for the performance and durability of the mortar in various applications.
  • Test methods: it references relevant ASTM test methods for determining properties like compressive strength (C109), bond strength (C1357), water retention, and air content (C185).
  • Sampling and testing frequency: it outlines procedures for sampling and testing to ensure compliance with the specification.
  • Packaging and marking: it specifies requirements for packaging, marking, and storage of mortar cement.

Essentially, ASTM C1329 aims to ensure the quality and consistency of mortar cement used in construction. By adhering to this standard, manufacturers can produce mortar cement that meets the specific needs of different masonry applications, and users can have confidence in the performance of the mortar.
