Properties of Cemented Tailings Backfill

A mathematical model is developed to predict and assess the evolution of the rheological properties of CPB under the coupled effects of temperature and progress of binder hydration. The prediction ability of the model is verified, and the validation test results show that there is good agreement between the predicted and experimentally measured rheological properties of CPB. The flowability of fresh CPB through a loop pipe has also been discussed. Furthermore, two mathematical models are developed to describe the thermo-hydraulic coupled behavior and thermo-hydro-mechanical behavior of hydrating CPB, respectively. Data from field and laboratory studies are employed to validate the developed two models. Some applications of the validated models are also presented.
