| Description: |
|
An
open graded coarse aggregate, produced by crushing and screening air cooled iron Blast
Furnace Slag. A light brown to gray
crystalline aggregate, formed simultaneously with the production of iron in a blast
furnace. The particles are sized from 2”
(50.0mm) to 3/4” (19.5mm). |

Usage Guide: |
| |
| The
4AA Blast Furnace Slag and M•DOT 6AAA coarse aggregate should be proportioned in the batch
plant into a 40 percent 4AA and 60 percent 6AAA by weight blend as detailed in the
“Grade P1 Modified” specification. The
coarse aggregates should then be blended into the concrete mixture along with the cement,
fine aggregate, water, admixtures and any special additives in the proportions detailed in
the mix design. Care needs to be taken to
maintain the moisture content of the 4AA Blast Furnace Slag at or above the absorption
level (3.5%-4.5%) so as to prevent the absorption of mix water into the Blast Furnace Slag
particles. |
