Investigation into the individual effects of temperature and sulphate ions on the fracture toughness of waste-based cemented paste backfill containing superplasticizer
Waste-based cemented paste backfill (WCPB) sustains long-term high dynamic loads in goafs, making modes I and II fracture toughness ( K IC and K IIC ) essential indicators for stability assessment. To optimize the transportation performance, superplasticizers are added to enhance slurry fluidity in engineering...
