Abstract

The shedi soil (Lithomargic clay) is the name given to the locally available silty sand which is abundantly available in the western coastal belt of Southern India, starting from Cochin to Goa. As long as this soil is confined and dry, there is a very little or no problem, but on the exposure in a cutting or when it comes in contact with water, it loses its strength drastically. Hence modification of this soil is necessary to reduce settlement and improve the bearing capacity. Quarry dust can be used as a substitute for sand to improve the properties of this soil. Due to the high demand for rubble and aggregates for construction purposes, rubble quarries and aggregate crushers are very common. Out of the different quarry wastes, quarry dust is one which is produced in abundance. Normally this waste product is left in huge heaps in the neighborhood of the quarry causing serious health hazards. In this background, any attempt to utilize this waste in developmental activities is relevant. The geotechnical characterization of quarry dust and its interaction behavior with soils can lead to viable solutions for its large-scale utilization and disposal. The evaluation involved in the determination of the geotechnical properties of the shedi soil from Kavoor of Dakshina Kannada District in its natural state as well as when mixed with the varying proportions of the quarry dust+ cement. The effects of stabilization on different properties of the soil with different degrees of additives are studied. The results showed that the geotechnical parameters of the shedi soils are improved substantially by the addition of quarry dust +cement. The results obtained in the present study will help to solve the problems associated with the shedi soils to a considerable extent and also utilization of the waste contributing towards economy in construction
