Revision of C1877-19 Standard Specification for Adhered Concrete Masonry Units


This ballot proposes several changes to the constituent materials section of C1877. While the constituent materials of the other C15.03 product specifications have recently harmonized, C1877 did not receive all of the harmonization changes. The following changes will harmonize C1877 with the other C15.03 product specifications:
1. Change ‘Materials’ to ‘Cementitious Materials’ at the start of the sentence in 4.1.
2. Clean up language relative to Modified Portland Cements in 4.1.2.
3. Change ‘Blast Furnace Slag Cement’ to ‘Slag Cement’ in 4.1.6 to conform to the current title of C989/C989M.
4. Clean up language relative to Aggregates in 4.2.
5. Clean up language relative to Other Constituents in 4.4.
