“…In this figure, the A line is an empirical boundary between inorganic clays -low-to-medium plasticity (CL) to high plasticity (CHI -and organic silts and clayslow plasticity (OL) to medium-to-high plasticity (OH) -which lie below it. The location of the B line shows an inorganic clay with extremely high plasticity (Almanza et al, (1989). The clay classifications for the various locations are shown in Table 1.…”

SUMMARYThis paper investigates the potential of using local clays and locally available materials as lining materials for solar ponds. Results for the liquid limit, the plastic limit, the plasticity index and the permeability were obtained for clays obtained from five regions in Jordan, namely Amman, Irbid, the Dead Sea, Karak and Tafilah. The results indicate that Amman clays have the lowest permeability values, making them a potential candidate as lining materials for solar ponds in Jordan. This paper also looks at various lining schemes for solar ponds, made of local clays and the other materials. The schemes were tested using saline water from the Dead Sea. It was found that an effective cheap lining scheme may consist of combinations of compacted local clay and locally manufactured low density polyethylene film sandwiched between the clay.

“…Under such circumstances, local clay deposits can be effectively utilized as an alternative for reducing liner costs and simultaneously preventing soil contamination, especially in developing countries [106]. A study by [107] indicated that compacted kaolinite clay had the same order of hydraulic conductivity as membrane liners for its application in large solar ponds. Compacted clay and low-density polyethylene (LDPE) were tested by [108] for their suitability as lining schemes in solar ponds.…”

“…Their results revealed that an LDPE film sandwiched between two layers of compacted clay could be utilized effectively as liners for solar ponds. Researchers such as [102,106,107,109,110] indicated that utilization of compacted soils as a substitute for synthetic materials for liner applications in solar ponds could lead to a reduction in the cost of construction and the risk of pollution to the subsoil and groundwater.…”

A critical reappraisal of residual soils as compacted soil liners

Compacted residual soils are often used as liner materials in engineered landfills, tailings dams, solar ponds, and canals, etc. to minimize the migration of contaminants into the surrounding environment and groundwater. To date, there has not been an extensive and adequate review of the suitability of different residual soil types for use as compacted liner materials. This paper reviews the suitability, merits, demerits, and possible applications of using expansive and lateritic residual soils as compacted soil liners. The review is then complemented by a study of the geotechnical properties of lateritic residual and shrinkable soils from Peninsular Malaysia. Suitability was assessed based on engineering property data for both soil types, collected from various journal papers, workshops, proceedings of conferences, and symposia from around the world. These properties were then compared with the standard requirements for use as liner materials. Descriptive statistics were employed to better assess the individual criteria of using both residual soil types as compacted soil liners. The results indicate that expansive and lateritic soils can be effectively utilized as liner materials if more acceptable materials are not readily available. The study addresses untreated soils but does not discuss the stabilization aspects.
