Strength Behaviour of Marine Clay Stabilized with Marble Dust and Quarry Dust

Abstract

AbstractMarine clay is found widely along the coastal area and demands expensive solutions in the construction of coastal highways. Marine clay has poor supporting capacity, and it further experiences large changes in volume on variations of moisture content. Hence, such soils need to be improved to make them suitable for road construction activities. Accumulation and safe disposal of various waste materials are a major concern to the environment. India has a large network of industries which produces millions of metric tonnes of industrial waste. Various soil stabilization techniques are used to enhance the engineering properties of the soil. Waste materials such as fly ash, rice husk ash, quarry dust, marble dust, pond ash, bagasse ash, and granulated blast furnace slag may be used for stabilization purposes. It is reported that the addition of such waste materials increases the physical as well as chemical properties of the weak subgrade soil. The investigation planned to be reported in the ensuing paper aims at presenting the improvement in properties of marine clay to be used as the subgrade, with the utilization of marble dust and quarry dust as a stabilizing agent.
