膨胀土是指在含水量变化的情况下具有体积增加或减少趋势的软质粘性土。这些土壤的水分含量的这种变化可能是由于从季风到夏季的季节性变化而发生的。它导致土壤在支持基础设施方面变得过于脆弱，导致各种失败的后果。本文试图通过纳米材料的处理来改善当地可获得的原位材料的工程性能。研究了纳米材料处理库塔纳德软粘土的压缩性、渗透性等工程性能，以及处理土的承载力的提高。软粘土与不同剂量的纳米化学品Terrasil混合，以产生土壤组合。最后，对制备的土组合进行了渗透性、击实性和固结强度试验，并对土组合进行了无侧限抗压强度（UCS）试验，得到了与峰值强度相对应的最佳化学剂用量。试验结果表明，纳米材料的掺入降低了软粘土的压缩性，提高了其抗压强度和渗透性。本工作的最终结果是找到使用纳米化学品进行软土地基改良的耐久性，并找到稳定剂的最佳剂量，以确保最大强度，控制压缩性和渗透性特性。
Expansive soils denote soft clayey soils that possess the tendency of increase or decrease in volume in the presence of moisture content changes. Such changes in the moisture content of these soils may occur due to seasonal variations from monsoon to summer. It causes the soil to become too weak in supporting the infrastructure facilities leads to consequences of various failures. This paper attempts to study is aimed to improve the Engineering performances of locally available in situ materials by treating it with Nanomaterial. Engineering performances such as the compressibility and permeability of Nanomaterial treated Kuttanad soft clay and an increase in supporting strength of treated soil. Soft clay mixed with different dosages of a nano chemical called Terrasil to produce the soil combinations. Finally, the experimental results have been carried out on prepared soil combinations to obtain permeability, compaction, and consolidation strength parameters.Further, Unconfined Compression Strength (UCS) tests were performed on soil combinations to arrive at the optimum dosage of chemical corresponds to peak strength. Experiment results are indicating that the addition of nano chemicals into the soft clay reduces the compressibility and increases UCS and permeability characteristics. The ultimate result of the present work is to find the durability of using a Nano chemical for soft ground improvement and to find an optimum dosage of the stabilizer, which ensures maximum strength, controlling compressibility, and permeability characteristics.
