A Study on Utilization of plastic waste strips with Cacl2 for Improving Weak Marine Clays

The soil found in the ocean bed is classified as marine soil. It can even be located onshore as well. India being peninsular country has alarge area coming under coastal region and also it has been the habitat for considerable percentage of population. The properties of marine soil depend significantly on its initial conditions. The properties of saturated marine soil differ significantly from moist soil and dry soil. Marine clay is microcrystalline in nature and clay minerals like chlorite, kaolinite and illite and non-clay minerals like quartz and feldspar are present in the soil. The soils have higher proportion of organic matters that acts as a cementing agent. The marine clays are found in the states of Andhra Pradesh, Karnataka, Kerala, Orissa, Maharashtra, West Bengal, Orissa, Tamilnadu 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 plastic waste strips 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 cacl2- plastic with varying percentages of the chosen materials for stabilization. The testing program will involve addition of different percentages of Cacl2 and plastic waste strips to marine clay and the results will be analyzed to assess the efficacy of the materials used.
