Abstract
Swelling soils are recognized as problematic soils that impose several challenges for civil engineers. When water leaks into these soils, their volume changes significantly, and they get dryer as the moisture content decreases. When based on such soils, lightly-loaded engineering constructions like sidewalks, railroads, single-story buildings, and pavements may sustain significant damages. In geotechnical engineering, it is important to study swelling soils and measure the pressure that results from their deformation as well as their capacity to swell. Swelling soils and rocks are generally found in arid and semiarid regions. The swelling tendencies of swelling soils are quantified by the swell potential and swelling pressure parameters. The swell pressure of a soil is the external pressure that needs to be placed over a swelling soil to prevent volume increase, while the swell potential of an swelling soil is the magnitude of heave of a soil for a given final moisture content and loading condition. In addition, existence of swelling soil which is unsuitable in construction sites. Seawater leaks into groundwater in coastal regions, changing its properties in a variety of ways including an increase in salinity and total dissolved solids. Swelling soil is used as barrier by different types of water to know its effect on atterberg limit and free swell index. Swelling soil is absorbent Aluminium Phyllosilicate essentially impure clay consisting mostly of montmorillonite, which it is the main component responsible for water absorption.
