Abstract: The present work has been carried out to study the effect of lime and marble slurry dust on geotechnical behavior of fine sand. Deserts and sea shores generally comprises of fine sand which not very effective for building infrastructure work or sub base work in road construction as it loose and vulnerable to collapse upon wetting. Fine sand is also unreliable for earthen dam construction as it has low shear strength and high permeability. Further, fine sand tend to absorb moisture from atmosphere which makes it constructing landfill liners and covers. The disposal of marble slurry dust from marble mines and cutting industries has been a major environmental concern over a period of last few decades. Marble dust can be used as an additive for soil stabilization. An experimental program including scanning electron micrographs and x-ray diffraction has been performed to characterize the materials. Various proportions of mixes of fine sand with marble slurry dust with various percentages of lime were tested to find out the optimum percentage of marble slurry dust in order to improve the strength characteristics of fine sand.
