Abstract: Cemented paste backfill (CPB) is a novel cementitious construction material that is used extensively for underground mine support and/or mine waste management worldwide. CPB consists of a mix of tailings (mine waste), ...

Abstract: Cement paste backfill (CPB) is an innovative technology of recycling mine waste (tailings) into construction materials to increase mine safety and productivity and promote sustainable mining. However, the application of ...

Abstract: Seasonal freeze–thaw (F–T) cycles significantly affect the mechanical properties of soils and the behavior of pile foundations in soils subjected to F–T cycles under different loading conditions. Soils exposed to F–T cycles ...

Abstract: This paper experimentally investigates the effect of internal sulfate exposure on the self-healing capacity of cemented paste backfill (CPB). CPB specimens were prepared with different sulfate concentrations of 0, 5,000, ...

Abstract: In underground mining practices, cemented paste backfill (CPB), a mixture of tailings, cement, and water, is widely adopted to fill extracted stopes. During and after the filling of the underground mine excavations or ...

Abstract: In this paper, the coupled effects of sulfate (chemical factor) and curing temperature (thermal factor) on the strength development of cemented paste backfill (slag-CPB) that contains ground granulated blast furnace slag ...

Abstract: Biocovers are a promising technology for mitigating methane (

Abstract: Biocovers are a promising technology for mitigating methane (CH4) emission from landfills. The geotechnical performance of the biocover material is one of the design criteria of biocovers. However, current understanding ...

Abstract: Cemented paste backfilling is a novel tailings-management method that is widely used in the mining industry to minimize the environmental and geotechnical risks associated with traditional mine-waste management techniques, ...

Abstract: This paper presents the findings from an experimental investigation that was conducted to assess the shear behavior and the changes in the shear behavior and strength parameters for cemented paste backfill (CPB)–CPB interface ...
