Grouting Mechanism of Cement-Based Slurry in a Concentric Annulus under High Groundwater Pressure by Weijie Zhang, Chenghao Han, Lianzhen Zhang, Jiuchuan Wei, Huiyong Yin, Weiwei Han, Chao Xie, Wenwu Zhou

“…In this study, an analytical governing equation of motion for the axial flow of an incompressible Newtonian fluid in a long concentric annulus is derived under the condition of high groundwater pressure. A stepwise calculation method is proposed to describe the grouting process based on two injection modes, namely, flow rate control and pressure control. …”

Waste Foundry Sand as Permeable and Low Permeable Barrier for Restriction of the Propagation of Lead and Nickel Ions in Groundwater by Ayad A. H. Faisal, Zaid Abed Al-Ridah, Laith A. Naji, Mu. Naushad, Hamed A. El-Serehy

“…This work aims to investigate the ability of using waste foundry sand (WFS) resulting as inexpensive by-product from steel industry in the low permeability barrier (LPB) and permeable reactive barrier (PRB) technologies for restriction of the movement of lead and nickel ions in the groundwater. Outputs of flask and tank tests certified that this material could capture these ions with sorption efficiency greater than 95% at time, pH, sorbent dosage, and speed equal to 60 min, 4 for lead and 6 for nickel, 2.5 g/100 mL, and 250 rpm, respectively. …”
