Abstract As a kind of green concrete, the mechanical properties and durability of cemented gangue backfill material
(CGBM) will be affected if they are in acid mine water with sulfate ions in the long term. To improve the performance of CGBM in acid mine water with sulfate ions, CGBM specimens with different doses of barium hydroxide were immersed in sulfuric acid solutions of different concentrations for 270 days. The changes of mass,
ultrasonic pulse velocity (UPV) and compressive strength of the specimens at different ages were analyzed. Scanning electron microscopy (SEM) and X-ray diffraction (XRD) were… More >
