Improvement of Engineering Properties of Cohesive Soil of Surendranagar By Adding Fly ash

Abstract

Urbanization and Transportation growth in the economy of India have led to the steep increase in the
construction activities and has necessitated the implementation of infrastructure project such as highway, railway, water
reservoir, reclamation etc. requires earth material in very large quantity. In urban areas, borrow earth is not easily
available. Quite often, large areas are covered with highly plastic and expansive soil like cohesive soil, which is not
suitable for such purpose. Various stabilizers’ are used such as lime, cement and calcium chloride. In the present
scenario fly ash has emerged as a one of the potential admixture to stabilize the soil. In the present work an attempt is
made to understand the effect of fly ash on various properties of cohesive soil. Fly ash is mixed in various proportions in
a parent soil. For these various proportions of fly ash different properties of soil are determined in laboratory and
compared with the parent expansive soil properties.
