ABSTRACT: Over the past decade, study of Cemented Paste Backfill (CPB), which is a mixture of mine tailings, binder, and water, has been increased. Despite all research has been done so far, many researchers have had difficulty in the study of the constitutive behavior of this material. The main reason is related to this fact that conducting laboratory scale test on this material, which can have a uniaxial compressive strength of less than 25 kPa in lower cement content and curing time, is troublesome. In this paper, challenges faced during conducting a high isotropic compression test on this material along with some design tips are discussed.
