Abstract:
The use of bentonite alone or amended with natural soils for construction of liners for water-retention and waste-containment facilities is very common. The importance of bentonite content in reducing the hydraulic conductivity of liners is well recognised. The study illustrates the role of the size of the coarser fraction in controlling the hydraulic conductivity of the clay liner. It has been shown that at low bentonite contents the hydraulic conductivity of the liner varies depending on the size of the coarser fraction apart from clay content. At a given clay content, the hydraulic conducti

Abstract:
In modern solid waste landfills, liner systems are essential structural elements that ensure that waste materials are safely separated from the environment. Many liner systems have been developed and used over the past decade. Among impermeable layers, clay liners are regarded as one of the very significant components of liner system and are being used worldwide as a waste containment system in landfills. One of the failures associated with clay liners is the occurrence of nonuniform settlements, resulting from the sudden collapse of waste, or the decomposition of waste materials, and (or) the

Abstract:
The factors that may affect short-term leakage through composite liners are examined. It is shown that the leakage through composite liners is only a very small fraction of that expected for either a geomembrane (GM) or clay liner (CL) alone. However, the calculated leakage through holes in a GM in direct contact with a clay liner is typically substantially smaller than that actually observed in the field. It is shown that calculated leakage taking account of typical connected wrinkle lengths observed in the field explains the observed field leakage through composite liners. Provided that care

Abstract:
The acceptance of compacted clay liners, from a management point of view, has been a source of major concern because of the uncertainty associated with the hydrogeologic properties of the clay. By examining the flux of leachate through the compacted clay liner of a typical engineered landfill, where the hydraulic conductivity of the clay is represented by a stochastic process, an acceptance protocol suitable for compacted clay landfill liners is derived. Determination of the equivalent hydraulic conductivity of the clay liner is accomplished by comparing the flux of leachate through a homogene

The clay swelling potential of sand-clay liners exposed to saline water or specific chemicals can influence their hydraulic conductivity and other consolidation properties.

Bentonite and cement grouts are chemicals that have a significant effect on the sand-clay liners.

Abstract:
Engineered synthetic liners on their own cannot protect the environment and human health against landfill leachate pollution. Despite their initial impermeability, they are susceptible to failure during and after installation and have no attenuation properties. Conversely, natural clay liners can attenuate leachate pollutants by sorption, redox transformations, biodegradation, precipitation, and filtration, decreasing the pollutant flux. Depending on the clay, significant differences exist in their shrinkage potential, sorption capacity, erosion resistance and permeability to fluids, which aff

Abstract:
Geosynthetic Clay Liners (GCLs) have been widely adopted in barrier systems for waste containment facilities. GCLs must be adequately hydrated at all times to maintain their low hydraulic conductivity. However, in several applications the GCL is subjected to high temperatures and its bentonite is therefore at risk of dehydration and desiccation. This is the case in landfills, brine ponds, solar ponds and tailing ponds. Higher desiccation risks have been found in artificial ponds exposed directly to solar radiation. This is due to higher temperature (sometimes >80oC), as well as lower overburde

To mitigate degradation, the only proven solution to date is the use of corrosion resistant alloys (CRA), either in homogeneous or clad/lined steel pipe product.

Full text
Abstract:
Pipeline failure due to corrosion is a common problem in the oil and gas and petrochemical industry. A cost-effective way to prevent these failures is the application of corrosion-resistant weld overlays (WOLs) onto the internal surface of line pipe. A WOL is a deposition of a filler metal - such as a nickel-base alloy - onto the surface of a part - usually carbon or low alloy steels - to introduce desired surface properties to the original substrate [1]. As such, the service life of the substrate is increased which results in reduced costs to industries such as oil and gas and petrochemical a
