This proposal would include text in Section 6.1.3 to clarify that slag used as a constituent of C595 blended cement shall be slag cement or granulated blast furnace slag. This ballot responds to withdrawn negatives on ASTM Committee C01 Ballot 2013-03, Item 1. Those negatives recommended additional clarification in Section 6 to assure that granulated blast-furnace slag is the ingredient permitted in C595 cements.
