Compacted soil–bentonite liners, consisting of a sandy soil mixed with bentonite as backfill, are used extensively as engineered barriers for contaminant containment. This paper studies the valorization of local materials containing calcareous sand, tuff obtained from Laghouat region (in the South Algeria), to associate with …

Accurate evaluation of unsaturated hydraulic conductivity (Kunsat) is critical in ensuring the reliability of the waste disposal structure. In this study, hydraulic conductivity of unsaturated specimens of compacted lateritic soil blended with bentonite at 0, 2.5, 5, 7.5 and 10% concentrations was determined by the Brooks & Corey-Burdine …

Hydraulic stone crusher, also known as a hydraulic cone crusher or hydraulic rock crusher, is a type of crushing machine used to crush stones and rocks into smaller sizes. It utilizes hydraulic pressure and a hydraulic cylinder to perform the crushing operation. A hydraulic cylinder, hydraulic power unit, and control panel make …

In general, the hydraulic performance of calcium bentonite was not significantly better than the performance of sodium bentonite for either the clay-amended sand or the GCL application, and was substantially worse than the performance of sodium bentonite in the bentonite-cement mixture. A drained angle of internal friction of 21° …

The hydraulic conductivity of the bentonite–sand mixtures decreased with increasing swelling pressure, and analysis revealed a strong correlation (R = 0.87). The relationships between the mixed NSAP replacement ratio to bentonite and hydraulic conductivity of the bentonite–sand–clay mineral mixtures are shown in Fig. 8.

In this study, the swelling pressure and hydraulic conductivity of bentonite–claystone mixtures with different bentonite fractions and dry densities were determined by carrying out infiltration tests under constant volume conditions. The results indicated that as the bentonite fraction and dry density increased, the overall swelling pressure ...

Hydraulic conductivity of polyanionic cellulose (PAC)–amended bentonite (PB) in calcium chloride (CaCl 2) solutions was investigated to access its chemical compatibility in vertical cutoff walls application.PB was synthesized by mixing conventional bentonite (CB) powder with PAC (2% dry weight).

Deep geological repository designed for the permanent disposal of high-level radioactive waste (HLW) is planned to be constructed in a stable rock stratum at a depth …

Adding bentonite amendments increased soil moisture, soil water storage and saturated hydraulic conductivity in the 0–60 cm layer. All bentonite amendments significantly (P < 0.05) increased above-ground biomass and grain yield, and improved water use efficiency in all five years. Above-ground biomass increases ranged from 2% …

Slurry trench cutoff walls, constructed using self-hardening slag-cement-bentonite (Slag-CB), are the most common form of in-ground vertical contaminant barrier in the U.K., Europe, and Japan, and are increasingly being used in the United States. This ...

The applicability of these methods to model thermal-hydraulic processes within the bentonite/crushed rock mixtures in a deep repository needs to be assessed. All experiments were conducted with mixtures containing sodium- (SPV Volclay) or calcium-bentonite (Calcigel) and we used water from Äspö. Hydraulic column experiments …

Such barriers include compacted liners that comprise bentonite-amended natural soils (i.e., sands, silts, and clays); manufactured geosynthetic clay liners (GCLs) that comprise thin (~ 10 mm) sheets of Na-bentonite sandwiched between two porous geotextiles; highly compacted bentonite buffers for high-level nuclear waste disposal; …

The effects of global climate change are becoming more evident and accelerating at an unprecedented pace. For this reason, human activities urgently need a paradigm shift to stop this entropic process before the consequences become irreversible. In this sense, the use of highly eco-efficient materials aimed at conveniently neutralizing …
