- Masonry cement Types N, S and M are covered by ASTM C91, Standard Specification for Masonry Cements.
Lehigh Hanson’s masonry cements consist of portland or blended cement, plasticizers, and an air-entraining agent. Air-entraining agents protect mortar from freeze-thaw damage and provide additional workability. The specific components of masonry cement may vary depending on the manufacturer and local construction practices. ASTM C91 defines masonry cement by physical requirements and performance properties rather than ingredients.
