Swell Behavior of Expansive Soils with Stabilized Fly Ash Columns

Darikandeh, F. / Viswanadham, B. V. S.

Abstract In this study, an attempt has been made to investigate the influence of flyash columns (FACs) on the expansive soil using different percentages of flyash and calcium carbide residue (CCR) to reduce heave of expansive soil bed. Puzzolanic activity of the binder admixture has been studied by replacing the columns admixture by sand in the vertical columns in the soil specimen. Conventional Oedometer tests have been performed. Free swell index (FSI) and particle size distribution tests have also been conducted as post-tests. It has been observed that swell properties considerably reduce with vertical fly ash columns in the expansive soil bed.
