Limed soils as a replacement for construction sand in stabilized sands

2015
ABSTRACT Sand is one of the main raw materials used in infrastructure and road construction. While it is a common natural raw material worldwide, the locations where it can be found are not evenly distributed. Natural sand can be extracted from the riverbed or from sandbanks in sea.

Multidirectional Movement of Chlorpyriphos in a Loamy Sand Soil

Bulletin of Environmental Contamination and Toxicology, 2000
movement in horizontal and upward directions in the soil it may improve its chances of reaching the insect pest present in the soil. The pattern of movement of any insecticide, besides being controlled by its chemical nature, is also dependent upon the soil texture.

Soil microbial community of abandoned sand fields

Folia Microbiologica, 2002
Microbiological evaluation of sandy grassland soils from two different stages of secondary succession on abandoned fields (4 and 8 years old fallow) was carried out as a part of research focused on restoration of semi-natural vegetation communities in Kiskunság National Park in Hungary.

Comparison of soil and sediment properties of a loamy sand soil

Soil Technology, 1997
Abstract Ten 25 m 2 runoff plots at the Hilton experimental site, east Shropshire, UK, have been used to compare the physicochemical properties of loamy sand plot soils and sediment eroded from the plots over one year. Sediment contained more sand (2 mm–60 μm) and less clay ( 2 mm) than soil.

Of Sand or Soil

2015
Why do tribal genealogies matter in modern-day Saudi Arabia? What compels the strivers and climbers of the new Saudi Arabia to want to prove their authentic descent from one or another prestigious Arabian tribe? This book looks at how genealogy and tribal belonging have informed the lives of past and present inhabitants of Saudi Arabia and how the ...

Pyrene and chrysene fate in surface soil and sand microcosms

Environmental Toxicology and Chemistry, 2001
Abstract Polycyclic aromatic hydrocarbons (PAHs) are major components of wastes from municipal gas plants and many wood preservatives. Soil contaminated with these wastes is a potential threat to human health because of the carcinogenicity of many PAHs.

Sorption of a Dispersed Dye by Sand and Soil

Journal of Environmental Quality, 1979
AbstractThe sorption of monoazo dye (a dispersed dye) by sand and calcareous soil is evaluated by laboratory batch and column tests for the purpose of obtaining quantative information needed for disposing of dyeing effluent. In the batch tests, the soil samples were added to dye solutions (or dispersions) having a concentration range of 25 to 125 mg ...

Chain-Soil Interaction in Carbonate Sand

Offshore Technology Conference, 2016
Abstract The design of mooring anchors of Floating LNG systems on Australia's North West Shelf (NWS) is challenging due to the high mooring loads and the seabed which comprises carbonate soils. Anchors with an embedded padeye require engineering of the chain inverse catenary and management of interfaces between the anchor and mooring ...

Soil Plug Behavior of Piles in Sand

Offshore Technology Conference, 1990
Abstract It has been proposed by Randolph (2) that granular soil plugs in open ended pipe piles can develop much greater resistances than allowed in present design (3). A simple mathematical model extending Randolph's concept to include load deformation behavior was developed and checked against more sophisticated ...
