Effects of mass concentration and curing age on the mechanical properties and damage evolution of aeolian sand backfill

Puntos clave

• Mechanical properties improve with higher mass concentration, enhancing structural integrity.
• Key findings indicate that as curing age increases, the damage evolution in aeolian sand backfill decreases significantly.
• Analysis of various mass concentrations and curing ages shows a clear relationship between these variables and material performance.
• Results imply the need for careful management of mass concentration and curing time in engineering applications.
