Effect of Fly Ash on the Mechanical Properties of Cemented Backfill Made with Brine

Sanshandao Xinli Gold Mine in Shandong Province is the first Chinese subsea gold mine. The mine uses cement backfill in the open stopes. The existence of a high concentration of Cl − in the water use to create the cement backfill affects its strength. An analysis by scanning electron microscopy and...
