Comparison Study of Geotechnical Behaviour of Lime Reinforced Pond Ashes Available in Delhi Region

Abstract

Pond ash is a pozzolanic material and can be stabilized with lime. It can also be stabilized with other commonly available stabilizers like cement, bentonite etc. This paper deals with both geotechnical characteristics of the pond ashes alone as collected from various thermal power stations in the National Capital Region, Delhi and also when they are stabilized using lime. The purpose of mixing this additive with pond ash is to improve the strength, deformability, volume stability (shrinking and swelling), permeability, erodibility, durability etc. of the mix for their use in the road construction.
