Tailings and Mine Waste Conference

Revisiting the large strain consolidation test for oil sands Jeeravipoolvarn, S.; Masala, S.; Zhang, C.; Moore, T.


The large strain consolidation test is a one-dimensional multi-step loading compression test used to obtain one-dimensional volume change properties of high water content material. These properties include compressibility (stress-strain behaviour) and hydraulic conductivity (ability to transmit water). The test is used worldwide for slurry and tailings work including for Alberta oil sands tailings since the 1970’s. This paper revisits this test method for use in the oil sands through the authors’ laboratory practice and a literature review. Key practical considerations and learnings are summarized to date.
