TREATMENT OF COLLAPSIBILITY OF GYPSEOUS SOIL

Journal of Engineering, 2008
A series of double odometer tests are conducted to study the compressibility and collapse ofgypseous soil taken from west of Baghdad governorate. The gypsum content of the soil used isnearly 25%. Four different types of additives are selected to reduce the collapse strain of this soil.These additives are cement, bentonite, calicium chloride and ...

Effects of habitat and land use on breeding season density of male Asian Houbara Chlamydotis macqueenii [PDF]

, 2016
Landscape-scale habitat and land-use influences on Asian Houbara Chlamydotis macqueenii (IUCN Vulnerable) remain unstudied, while estimating numbers of this cryptic, low-density, over-hunted species is challenging.

Mineralogical Composition of the Urinary Stones from Different Provinces in Iraq

The Scientific World Journal, Volume 5, Issue 1, Page 24-38, 2005., 2005
For this study, 25 samples of urinary stones were chosen from different provinces in Iraq as representative sampling localities. These samples of urinary stones were collected to represent kidney, urate, and bladder stones. The main objectives of this study are to try to shed some light on the possibilities of tracking down the effective environmental ...

Soil development and ancient Maya land use in the tropical karst landscape: Case of Busiljá, Chiapas, México

Soil Science Society of America Journal, Volume 88, Issue 5, Page 1561-1582, September/October 2024.
Abstract The soil mantle of the tropical karstic landscapes of Southern Mexico was shaped by specific processes of pedogenesis and long‐term human impacts of ancient Maya agriculture. To understand the interaction between natural and human‐induced soil‐forming processes in the calcareous mountains of Chiapas state, we studied soil toposequences around ...

Envelope of Collapse in Gypseous Sandy Soils using Finite Element Method and Particle Image Velocimetry

Journal of Engineering
Water level rise as well as inundation to gypseous soil medium can lead to a substantial loss of volume of the soil, with or without adding load. Macromechanical behavior of gypseous sandy soils using particle image velocimetry (PIV) is yet to be ...

FREEZE-THAW BEHAVIOR OF GYPSEOUS SOIL

ZANCO JOURNAL OF PURE AND APPLIED SCIENCES, 2019
This research work studied the influence of freeze-thaw (F-T) cycles and gypsum percent on the mechanical properties and durability of clayey soil. Different amount of gypsum percent (varied between 0-25%) was added to the clayey soil and subjected to 12 F-T cycles.

Behavior of Piled Raft Foundation Model Embedded within a Gypseous Soil Before and after Soaking [PDF]

Engineering and Technology Journal, 2017
The paper explain an experimental study to show piled raft system behavior when embedded within gypseous soil in three different stats (dry, socking for 1 day and placing a bearing layer of dense sand below the gypseous soil when socking for 1 day).
