Early-age strength evolution and brittle-to-ductile transition mechanism of basalt-fiber-reinforced cemented gangue backfill

Abstract High brittleness and rapid post-peak capacity loss are often observed in cemented gangue backfill (CGB) under uniaxial compression. The risk of sudden instability in deep mining panels is therefore increased. Chopped basalt fibers (0-0.60 wt%) were incorporated to improve early-age load cap...
