RISEffects of Polymer Treatment on Undrained Strengths and Cyclic Behavior of a Low-Plasticity Slurry
Publisher: American Society of Civil Engineers
Laboratory Evaluation of Lateral Swelling Pressure
Publisher: American Society of Civil Engineers
Abstract: A laboratory technique for the determination of the lateral swelling pressure of expansive clays is described. The method uses a hydraulic triaxial cell fitted with a lateral strain belt, and is based on the ``Method of ...

A Unified Approach for the Analysis of CPT Partial Drainage Effects within a Critical State Soil Mechanics Framework in Mine Tailings
Publisher: American Society of Civil Engineers
Abstract: Results from both laboratory and in-situ cone penetration tests (CPTs) on predominantly sandy silt platinum tailings from an operational mine in South Africa are reported. The CPTs were conducted with four different cone ...

Behavior of Cemented Paste Backfill in Two Mine Stopes: Measurements and Modeling
Publisher: American Society of Civil Engineers
Abstract: Over the past decade there has been increasing use of “paste” for backfilling of mined-out voids (“stopes”) in underground mines. Paste backfill is generated from full stream tailings and is almost always placed underground ...

Experimental Study of the Evolution of the Soil Water Retention Curve for Granular Material Undergoing Cement Hydration
Publisher: American Society of Civil Engineers
Abstract: The evolution of the soil-water retention curve (SWRC) for cemented paste backfill (CPB) undergoing cement hydration is evaluated in this paper. A pressure plate apparatus and insertion tensiometers in a continuous drying ...
Numerical Modeling of Cemented Mine Backfill Deposition
Publisher: American Society of Civil Engineers
Abstract: In current underground mining practice, it is common to use tailings, without added cement, to fill mined-out voids (“stopes”). If fine-grained tailings are used, the high placement rates and low permeability can often ...
