blast furnace slag crushing and screening : Blast furnace slag
Gradation: Blast furnace slag should be crushed and screened to produce a material that satisfies the grading requirements of granular base and subbase specifications, such as AASHTO M147. Compacted Density : The compacted density varies with size and grading of the slag, method of measuring, and bulk specific gravity of the slag.

Blast Furnace Slag. Blast furnace slag is used successfully in mud-to-cement conversion worldwide because of its economic, technical, and environmental advantages (Pessier et al., 1994). Slag-mix slurries were used as primary, temporary abandonment and sidetrack plug cements during prospect predrilling in the Gulf of Mexico.
