In order to study the shrinkage process of clayey soil, we perform a modified laboratory test allowing to measure simultaneously and continuously the vertical displacement and the weight of natural state specimen. The experiment was conducted on undisturbed clayey specimen. Using the experimental results, and on the basis of the existing relation between the soil water content and its structura...

Background: Geotechnical engineers working on the ground face a common obstacle of unsuitable soil. Expansive soil is one soils vulnerable to high loads and unstable. Properties such as permeability, low bearing capacity, compression, swelling shrinkage behavior, strength stiffness are all characteristics an expanding weaker than other types due these characteristics. Objective: T...

This study was conducted to have a detailed analysis of the geotechnical properties expansive soil and fly ash from Sipat thermal power plant. It reported findings laboratory studies on certain common physical properties. The chemical morphology black cotton (BCS) is also determined using scanning electron microscopy X-ray diffraction test. test includes determining specific gravity, particle s...

Loss of matric suction during rain has an important effect on the instability expansive soil slope. A new device was designed for testing force in order to propose and determine equivalent corresponding suction. First, internal relation between unsaturated analyzed. Then, numerical algorithm implementation discussed, introduced into strength reduction finite element method (FEM). Finally, effec...

been widely researched as surface and deep soil treatment techniques (Figure 1). For certain practical situations, such as house foundations on expansive soil, mixing is not possible. Current research has shown that chemical treatment using a potential difference to transport chemical ions between bespoke electrodes can overcome such problems, whilst achieving the desired results. However, a ma...

Expansive soils are found in many parts of the world that especially arid and semi-arid regions. They have caused several damages lightweight structures for decades. For this reason, a more suitable foundation type should be selected designed built on these soils. example, application belled shaft at expansive soil layer is preferable method practice. However, one worst cases design accepted sw...
