The Role Of Coal Gangue Ultrafine Powder In Cement

Calcined coal gangue powder was used to partially replace Portland cement (PC) at 10 , 20 , 30 , and 40 by weight. The water to binder ratio (w b) of 0.5 was used for all the blended cement paste mixes. The reaction degree of calcined coal gangue powder in calcined coal gangue powder cement (AC) was determined using a selective dissolution method.

The Effect Of Acid Mine Drainage Corrosion On The Creep

The Effect Of Acid Mine Drainage Corrosion On The Creep

Oct 20, 2020 Acid mine drainage (AMD) is a hazardous by-product of coal mining, which may intensify the creep deformation of cemented gangue backfill (CGB) in solid backfill mining. In this study, the long-term stability and creep property of CGB soaked in AMD were quantitatively measured by experimental and theoretical analysis. The uniaxial compressive strength, elastic modulus, and mass of CGB.
