What is the strength classification for Type N masonry?

Type N masonry is classified as medium strength and is commonly used for a variety of applications in masonry construction. This classification is particularly important because it indicates the material's compressive strength, which is usually in the range of about 750 to 1,000 psi.

This medium strength makes Type N mortar well-suited for use in above-grade walls that are exposed to moderate weather conditions. It typically provides a balance between strength and workability, allowing for sufficient bonding with masonry units while still being flexible enough to accommodate slight movements without cracking.

In contrast, other types of masonry have specific applications that require different strength classifications. High strength, for example, is reserved for situations where structural loads are significant, while low strength might be suitable for non-structural applications where flexibility is more critical than load-bearing capacity. Understanding these classifications helps masonry professionals choose the right materials for their projects based on the specific requirements of construction.
