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.
