Question regarding interpretation of notes in Fine Aggregate Gradation Chart

[oengineer]

I have a question regarding the interpretation of the note (see highlighted text) provided for the Fine Aggregate Gradation Chart shown in the image:

I am seeking clarification on what is meant by "0-6 for manufactured sand" & "6-35 when sand equivalent value is greater than 85" in the image above.

Suggestions/comments are appreciated.

Oh sorry, I figured it out. Silly question.

They are talking about the ranges for Sieve Size #50 and #200.

Never mind.

Yes, that's it; however, the first paragraph allows the use of slag....that needs to be clarified as to the types of acceptable slag. Some slags are highly expansive (foundry sand, electric arc steel slag, etc.)
