SAND: An Additive for Stabilzation of Swelling Clay Soils
Clay Soils Bentonite Sand Swell Stabilization
2013/3/11
An experimental program carried out in this study seeks to understand the physical mechanisms of stabilization of an expansive soil by adding an inert material (sand) at various forms; mixing and inte...
Evidence of microbial activity in siderite and calcite deposits on gastropod shells in Pliocene sand and clay beds from Lipovljani,Croatia
concretions fresh water diagenesis iron bacteria calcite siderite Pliocene Slavonia Croatia
2009/12/8
Freshwater Pliocene sand and clays found near Lipovljani in western Slavonia, Croatia, contain gastropods preserved by diagenetic mineral incrustations of alternating calcite and siderite. The geochem...

Slope stability assessment of weathered clay by using field data and computer modelling: a case study from Budapest
Slope stability assessment weathered clay field data computer modelling
2009/12/30
A future development site of a housing estate, an abandoned-brick yard with clayey slopes was studied in details to assess slope stability and to calculate the factor of safety. The Oligocene clay, th...
Softening and instability of natural slopes in highly fissured plastic clay shales
Softening instability natural slopes highly fissured plastic clay shales
2009/12/29
Softening is often considered to be the main cause of first-time slides in OC clay, but so far the mechanics of softening has not been satisfactorily explained. Bearing on laboratory data and field ob...
