- Effect of specimen composition on the strength development in cemented paste backfill (2006, background): “These reactions typically form secondary ettringite, gypsum, and monosulfoaluminate, which are highly expansive products that generate high internal pressures, thereby deteriorating the strength of cemented paste backfill (Fall and Benzaazoua 2005).”
- A contribution to understanding the effects of curing temperature on the mechanical properties of mine cemented tailings backfill (2010, background): “It may also be possible to combine the tailings with other sands of different sizes to affect the coefficient of uniformity Cu and the coefficient of curvature Cc to improve compressive and tensile strength (Fall and Benzaazoua, 2005) for cemented backfill.”
- Coupled effects of sulphate and temperature on the strength development of cemented tailings backfills: Portland cement-paste backfill (2010, background): “Furthermore, the addition of gypsum (CaSO4 2H2O) or anhydrite (CaSO4) to the clinker to control the setting of the cement can introduce small amounts of sulphate into the CPB mix [15,26].”
- Coupling temperature, cement hydration and rheological behaviour of fresh cemented paste backfill (2013, background): “Therefore, this useful mining operation which is associated with the technology of cemented paste backfill (CPB, a mixture of binders, water and tailings) is being widely and intensively employed in the practice of underground mining around the world (e.g., Bloss, 2002; Kesimal et al., 2003; Kesimal”
- Saturated hydraulic conductivity of cemented paste backfill (2009, background): “This can be attributed to the fact that high sulphate concentrations inhibit cement hydration at early ages (Fall and Benzaazoua, 2005), which in turn, results in the formation of”
