Influence of Air Entraining Agent on Strength and Microstructure Properties of Cemented Paste Backfill

The conveying distance during the backfill operation has become extensively large with the advancement of mining work. It requires the immediate attention of academic and industrial communities. Adding air entraining agent (AEA) can improve the rheological properties of the filling slurry and facili...
