Rheological properties, mechanical characteristics, and microstructures of gangue-cemented paste backfill: Linking to loess doses

Efficient and sustainable development is the core of green mining. In this paper, natural loess (LO), fly ash (FA), gangue (GA), ordinary Portland cement (OPC), and mixing water were used to prepare gangue-cemented paste backfill (GCPB) for underground filling mining. To investigate the effect of pa...
