“…The effect of coir fiber to shrinkage strain is not much differing compared to coir pith condition. From the test results, it is evident that volumetric shrinkage had reduced from 72% to 61% and linear shrinkage values had declined from 48% to 22% but in diametric direction the shrinkage does not change with addition of coir fiber [6].…”

“…The properties of saturated marine soil differ considerably from moist soil and dry soil. The shrinkage characteristics of expansive soil stabilized with coir waste material is studied [6]. Clay soil is procured from Cochin marine basin from a depth of 1 m. The soil is powdered to a size less than 4.75 mm and it is sun dried to reduce the moisture content in the soil to 0%.…”

Expansive soils are the soils that expand when comes in contact with water and shrinks when the water within them gets evaporates. These soil are treated as problematic soils for various construction activities hence there is an essential to improve its strength against load effects and also to alter their behaviour against moisture conditions. This review aimed to study the behaviour of expansive soil stabilized using various natural and industrial processed materials such as cement, polymer, lime, rice husk ash, stone dust, fly ash, coir fiber and its pith, jute, bagasse ash and ground granulated blast furnace slag (GGBS). The paper covers the discussion on experimental test results of black cotton soil conducted by various researchers. The tests being basic geotechnical properties, maximum dry density and optimum moisture content, unconfined compressive strength test (UCS), California bearing ratio (CBR), etc., are presented.

“…The fraction which was passed through the sieve is taken for the study. The specific gravity of coir pith is 0.12 [5] and the average length of the fibre is 10mm. Chemical composition of coir fibre which is contained in coir pith is lignin 45.84%, water soluble…”

“…Conventionally the volume change behaviour of soil is measured either by using shrinkage characteristics or swelling characteristics. [1]. Stabilization of highly expansive clay is, in particular an area of major interest to the construction community due to excess swelling and shrinkage experienced by this clay upon changes in moisture content [2].…”

Stabilization of black cotton soil is a challenging task for geotechnical engineers since such soil is highly vulnerable to expansive characteristics when the moisture content is increased. Due to its expansive nature, it is also called as swelling or expansive soils. Among the clay minerals, Montmorillonite is mainly responsible for such expansive characteristics. Bore log profile has a cluster of soil specimens including black cotton soil also which is unavoidable. Soil engineers have a serious concern about such expansive soil since it is treacherous for foundation of buildings. To overcome such deficiencies it becomes essential to stabilize the soil conditions. The commonly employed methods to decrease the expansive behaviour are: Chemical stabilization, Mechanical stabilization and installation of moisture barriers. In this paper, chemical stabilization method is adopted. Soil stabilizers, namely, sodium silicate, epoxy resin and polyvinyl alcohol are chosen and are mixed with black cotton soil in varying proportions of 5%, 10% and 15% to study the changes in geotechnical properties. From the results it is evident that polymer treated soils reduce plasticity characteristics and shows better results in geotechnical properties.
