The study of the collapse soils under effect flooding is a major problem in soil ‎mechanics. Most work done on treatment these has been devoted to ‎the use binders hydraulic or organic types. However, little salt calcium chloride ‎collapsible treatments.‎ purpose this evaluate reconstituted collapsible laboratory, at ‎different levels water content, compaction energy and concentration saline so...

One of the Iraqi geotechnical problems is presence gypseous soils covering about (27-36) percentage Iraq containing gypsum between (10-70) ratios. The main reason for soil problematic dissolution when these are inundated. However, soluble can be leached out particles, so led to cracking, tilting, and collapsing related structure changing properties. aim this work investigate performance under-r...

Abstract Gypseous soil is located in dry and semi-arid areas unsaturated conditions this type of becomes a serious issue for engineering geotechnical when it wet. the properties structure change, exposed to soaking leaching, because gypsum dissolved water causing rupture bonds that hold particles together reduction suction power holds them together. Large settlements potential collapse will hap...

We analyzed the characteristics of red soils that are often considered collapsible soils. In this study, we examined depositional environment and lithologic characteristics, stratigraphy, conducted mechanical sieve, X-ray fluorescence, X-Ray diffraction, scanning electron microscope, fluorescence analyses optically stimulated luminescence dating. The samples were collected from gravel pits to e...

Collapsible soils are susceptible to large volumetric strains when they become saturated. Numerous soil types fall in the general category of collapsible soils, including gypseous which is characterized by relatively low density, appreciable strength and stiffness dry state, but significant deformations as a result wetting. The aim this study investigate effectiveness curing period time carbona...

The presence of gypsum in soil has a high effect on the mechanical and physical properties soil. This depends fundamentally type quantity existent present study attempts to improve gypseous using new pozzolanic material discovered as from attapulgite clay. It is called “High Reactivity Attapulgite” HRA. objective this investigate ability be moderate stabilizer used for treating was obtained one...
