Abstract

Marine clay deposits are found both in the coast and in several offshore areas spread over many parts of the world. India being peninsular country has a large area coming under coastal region and also it has been the habitat for considerable percentage of population. The marine clays are found in the states of West Bengal, Orissa, Andhra Pradesh, Tamilnadu, Kerala, Karnataka, Maharashtra and some parts of Gujarat. These soils are highly saturated, soft, sensitive and normally consolidated. These usually have low density and low shear strength in nature. This project will investigate the possibility of utilizing sawdust and lime to reinforce stabilized weak marine clays to pave way for its use in civil engineering projects such as in road bases, embankments etc.. A series of tests will be done on weak soil-lime-sawdust with varying percentages of the chosen materials for stabilization. The testing programme will involve addition of different percentages of lime and sawdust to marine clay and the results will be analyzed to assess the efficacy of the materials.
