Masonry cement consists 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. Mortar cement, a relatively new designation, was developed for demanding structural applications and features higher strength and lower air content than masonry cement. It is the only cement for mortar that must meet a minimum bond strength. For that reason, it conforms to a separate ASTM designation, C1329, Standard Specification for mortar cement.
