Mechanical behavior and failure mechanisms of waste rock-phosphogypsum cemented backfill
This study examines the mechanical properties and failure mechanisms of cemented backfill materials made from waste rock and phosphogypsum. Researchers found that larger aggregate sizes significantly increase peak strength and elastic modulus, while higher phosphogypsum content tends to weaken the material.
Why it matters
Optimizing backfill materials is critical for sustainable mining practices and the safe disposal of industrial waste products like phosphogypsum.
