Behavior of Gypseous Soil Treated by Arabic Gum Biopolymer Under Cycles of Wetting and Drying [PDF]
Tikrit Journal of Engineering SciencesGypseous soil is classified as problematic soil since the main source that makes it problematic soil is the dissolving of gypsum in water. Treatment by biopolymers offers an environmentally friendly and sustainable way of soil enhancement that has ...

Collapsibility of Gypseous Soil Treated with Pectin‐Biopolymer through Leaching
Journal of Engineering, Volume 2023, Issue 1, 2023., 2023 Gypsum reinforcement in dry soil provides activity resistance. It quickly becomes a source of danger in the conditions of partial and complete soaking of gypsum soil as a result of the dissolution of gypsum, which poses a great danger to the structures built on this soil.

Numerical Study on Load Bearing Capacity of Root‐Caisson Foundation
Mathematical Problems in Engineering, Volume 2023, Issue 1, 2023., 2023 Innovation has been made in the caisson foundation to support a very large structure resting over a soft soil stratum known as the root‐caisson foundation. This technique was executed in China‐Yangtze River Bridge. The root caisson foundation was first implemented in the Yangtze River bridge and discovered that the root improves soil structure ...

Ceropegia longirostris sp. nov. (Apocynaceae–Asclepiadoideae) from Ethiopia and Kenya
Nordic Journal of Botany, Volume 39, Issue 12, December 2021., 2021 The new species Ceropegia longirostris Thulin, M.G.Gilbert & Kaariye is described, illustrated and mapped. It is known from two localities, one on gypsum in the Somali National Regional State (Ogaden) in southeastern Ethiopia and one, based on a photographic record, from just east of Lake Turkana in northwestern Kenya. The new species is a member of C.

Two new species of Commicarpus (Nyctaginaceae) from the Horn of Africa
Nordic Journal of Botany, Volume 39, Issue 4, April 2021., 2021 The new species Commicarpus altus Thulin from central Somalia and C. ogadenensis Thulin from southeastern Ethiopia are described, illustrated and mapped. Both species are shrubs with succulent leaves and white flowers, and they have previously been treated as forms of the widespread and variable C. plumbagineus (Cav.) Standl. Commicarpus altus is found

Advances in Civil Engineering, Volume 2021, Issue 1, 2021., 2021 There are a large number of high‐filled and deep‐dug highways in loess areas. The differential settlement between the filled and undisturbed soils is the main cause of damage. Bamboo grids are good reinforcement and flexural tensile materials for highway subgrades, and the properties of the interface between the bamboo grid and loess soil affect the ...

Advances in Civil Engineering, Volume 2021, Issue 1, 2021., 2021 The focus of this study was to investigate the effect of loess soil treated with lime on the lateral‐seepage response. Three groups of box experiments were carried out to study the lateral‐seepage effect under different types of loess‐lime structures. Automated testing systems were designed to perform experiments and collect data.
