Deposition and transport of functionalized carbon nanotubes in water-saturated sand columns [PDF]

open access: yes, 2012
Knowledge of the fate and transport of functionalized carbon nanotubes (CNTs) in porous media is crucial to understand their environmental impacts. In this study, laboratory column and modeling experiments were conducted to mechanistically compare the ...

Dependence of the phosphate sorption capacity on the aluminium and iron in Finnish soils

open access: yesAgricultural and Food Science, 1963
An attempt was made to study to what extent the capacity of the more or less acid soils in Finland to sorb phosphate may be explained on the basis of their content of aluminium and iron.

Triaxial compression tests on a crushable sand in dry and wet conditions [PDF]

open access: yes, 2015
A calcareous sand from the Persian Gulf is subjected to a series of dry and fully drained saturated triaxial shear tests. The samples are prepared at relative densities of 65% and either left dry or saturated. They are consolidated to confining pressures

Behaviour of micropiles in heterogeneous coarse soils [PDF]

open access: yes, 2016
This paper reports on an experimental investigation on the behaviour of small-diameter piles, commonly referred to as micropiles. This particular type of deep foundation is frequently used in many barely accessible Italian mountainous areas, often ...

Geotechnical viability of sand, cement, and binary stabilisation of soils in the western Niger Delta; An example of Warri City, Southern Nigeria

open access: yesJournal of the Geological Survey of Brazil
The pavement performance of superficial soils in southern Nigeria is in decline, most notably due to the use of inferior pavement materials and poor soil conditions.

An elastoplastic model for unsaturated expansive soils based on shakedown concept [PDF]

open access: yes, 2013
It is important to model the behaviour of unsaturated expansive soils subjected to hydromechanical loadings, because these wetting and drying cycles alter significantly their hydromechanical behaviour which may cause a huge differential settlement on the ...

Soil particle-size analysis: A comparison of two methods [PDF]

open access: yes, 2003
Knowing the proportion of particle sizes in soil is important to soil scientists and agronomists. The mixture of sand, silt, and clay influences water movement, solute transport, nutrient retention, and many other properties and processes in soil.

Laboratory study on the effects of hydraulic and granulometric parameters on the response of granular soil to internal erosion [PDF]

open access: yes, 2019
Erosion is a major environmental problem to agricultural land as well as to civil engineering infrastructures. Rainwater infiltration into granular soils can lead to the migration of fine particles by suffusion.
