Effect of Terrasil on Geotechnical Properties of Expansive Soil Mixed With Lime
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 1
Abstract
Expansive soil is considered as the problematic soil for most of construction activities because of its expansive behaviour. Thus this type of soil needs to be treated prior to any construction activities. There are many way to solve this problematic behaviour of expansive soil. Soil stabilization is one of the technique to improve the geotechnical behaviour of expansive soil. This paper presents the effect of Terrasil on the geotechnical properties of black cotton soil treated with lime. The present study is aimed at determining the geotechnical behaviour of black cotton soil-lime mixture with variation of a nanochemical called Terrasil. The Terrasil content was varied from 0.05 to 0.09 % by the weight of dry soil, while the lime is used as a base stabilizer in quantity equals to 2% by weight of dry soil. The results indicated that the unconfined compressive strength (UCC) and CBR values of black cotton soil can be increased by the addition of terrasil and lime. The increase in unconfined compressive strength and CBR values was highest with 0.07 % terrasil. Thus the behaviour of black cotton soil in response to construction activities can be improved with the addition of terrasil as a stabilizer.
