Laboratory Investigation on Dynamic Small-Strain Shear Modulus of Fly Ash Stabilized Expansive Soil
The shrink–swell property exhibited by expansive/collapsible soils is mainly due to the presence of certain clay minerals. This leads to sudden change in strength and stiffness of soil underneath the foundation and ultimately causes the premature failure of a structure. An experimental probe was carried out to study the swelling and stiffness characteristics of black cotton soil by inclusion of class F fly ash. The percentage of fly ash was varied between 2 to 20%. A set of bender element test was conducted to study the dynamic properties of fly ash stabilized soils for different curing periods. It has been found that the curing period does not influence the small-strain modulus of fly ash stabilized specimens significantly. However, the small-strain stiffness of soil is intensified with increasing fly ash content. Moreover, the free swell index decreases with increasing fly ash content in BC soil.
