Liquefaction is a phenomenon in which the strength and stiffness of a soil is reduced by earthquake shaking or other rapid loading. Liquefaction and The tropics are as beautiful and diverse below-ground as they are above-ground. Learn how to use knowledge about the natural variability in soil properties for Organic horizons occur in Organic soils or they may be present at the surface of mineral soils. There are two groups of organic horizons – those that are formed in In some cases, silty clay loam and sandy clay loam.

Expansive soil

Expansive soil is defined as partially saturated plastic soil that exhibits high volume change when its environmental conditions are Corex slag was mixed with the expansive soil in the range of 10% to 30% with an increment of 5%. Lime was added by 2% and 4% in the mix by the dry weight of Soils that exhibit changes in volume with changing moisture content are called expansive soils. The capacity of a soil to shrink and swell is related to the clay The main factor that governs the shrink-swell behavior of expansive soils is the change in water content and the amount and type of clay size in the soil. 4 Jan 2021 Volumetric changes in expansive soils due to seasonal moisture changes can seriously damage foundations. In the small-scale laboratory 27 Mar 2021 Expansive soils are responsible for more damage to buildings than any other natural hazard.

1 INTRODUCTION The capital of Saskatchewan, Canada, is founded on a glacio-lacustrine clay deposit that exhibits significant volume changes due to seasonal weather variations. Alternate swelling and shrinkage in the expansive Regina clay has impaired civil Expansive soils are one of the nation’s most prevalent causes of damage to buildings and construction. Annual losses are estimated in the range of $2 billion. The losses include severe structural damage, cracked driveways, sidewalks and basement floors, heaving of roads and highway structures, condemnation of buildings, and disruption of pipelines and sewer lines.

Treating expansive soil is necessary because clay soil particles attract moisture and hold on to it, producing a swelling mass of soil and water. When the moisture dissipates from the soil, the particles come back together, causing a shrinking action of the soil mass. Expansive soil is known as problematic soil causing detrimental effect on pavement system.
