Effect of Lime and Brick Ash Inclusion on Engineering Behaviour of Expansive Soil

Many major states of India have large deposits of expansive soil. We all know how difficult it is to work with expansive soil due of its unpredictable shrinkage and swelling behaviour. This uncertain behaviour causes major uplift pressure and stresses on the structure overlying on it. The presence of the mineral montmorillonite is responsible for the expansive soil’s behaviour. Soil stabilization is the technique which is used to deal with problems associated with expansive soil. This research aimed to utilize industrial waste brick ash (that is produced during the production of bricks) in stabilization of the expansive soil with Lime. Brick ash can significantly improve the engineering characteristics of expansive soil.
