Effect of Marble Dust and Burnt Brick Dust on Characteristics of Black Cotton Soil

Soil stabilization is a technique aimed at increasing or maintaining the stability of soil mass and chemical alteration of soil to enhance their engineering properties. Stabilization allows for the establishment of design criteria as well as the determination of the proper chemical additive and admixture rate to be used in order to achieve the desired engineering properties. Benefits of the stabilization process can include higher resistance values, reduction in plasticity, lower permeability, reduction of pavement thickness, elimination of excavation material hauling or handling. Stabilization of expansive soils with admixtures controls the potential of soils for a change in volume, and improves the strength of soils. The effects of burnt brick dust and marble dust on MDD, OMC, soaked CBR of expansive soil stabilized with MD and BDD has been found to be limited in literature. The objective of this paper is to study the effects of marble dust on MDD, OMC, soaked CBR, of an expansive soil stabilized with optimum percentage of MD and BDD. The effects of unsoake and soaked CBR value have been studied.
