Experimental Study of Consolidation Behavior of Mature Fine Tailings Treated with Microbial Induced Calcium Carbonate Precipitation
Mature fine tailings (MFT) are by-products from oil sands extraction processes and pose a challenge to the geo-environmental community. Large impoundments are required to store MFT due to physical characteristics of the material, namely the high volume of the water in tailings and large-strain consolidation behavior. Microbial induced calcium carbonate precipitation (MICP) treatment has been previously demonstrated to effectively accelerate the dewatering process of the MFT; however, the change to the consolidation behavior of the MFT after MICP treatments has not been examined. In this paper, slurry consolidometers are constructed to evaluate the compressibility and permeability properties of MFT after MICP treatment. The presented test results indicate MICP can help accelerate the settlement of MFT by developing the soil skeleton with a minimal decrease in permeability.
