This is to propose changing the name of ASTM C897 to "Standard Specification for Aggregate for Job-Mixed Portland Cement Based Plasters" to "Standard Specification for Aggregate for Job-Mixed Cement Based Plasters". The change will delete the word Portland from the Standard's title.
C897 3.3.2.1 states "plastic cement, n - a hydraulic cement, primarily used in portland cement based plastering construction, consisting of a mixture of portland or blended hydraulic cement...".
Stucco cement is manufactured with both Portland Cement - ASTM C150 and with Blended Cement - ASTM C595. In many sections of the world Portland Cement is no longer produced, or is produced in very limited quantity. Most C1328 Stucco Cements contain Blended cement. Therefore it is correct to delete "Portland" from the Standard's title to include both cements.
