In the last five decades, rise of plastic industry led to increase in waste environment, therefore scientists were thinking reduce by recycling plastic. On other hand, there is a problem collapse gypseous collapsible soil upon wetting. this paper, one methods adopted improve mixing with 1% fiber shear strength and collapsibility at state saturation or The used classified as SW-SM, gypsum conten...

Drylands typically have distinctive vegetative patterns that reflect the underlying physical landscape. We use a geopedological classification to organize the landscape into five categories from broad scale to fine scale: (1) physiographic divisions which describe regional topography, such as mountains and basin floors; (2) regolith type which identifies residuum versus transported sediments; (...

Abstract Gypseous soils are considered one of the most problematic soils. The skirted foundation is an alternative technology that works to improve bearing capacity and reduce settlement. This paper investigates use square foundations resting on gypseous soil subjected concentric eccentric vertical load with eccentricity values 4, 8, 17 mm in 16 experimental model tests. To obtain results by us...

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...
