Abstract - Industrial effluents released by various industries is a major problem today. These effluents are disposed either treated or untreated over land. Then it interacts with the soil and environment. This causes variation in geotechnical properties of soil. This variation can affect the construction and safety of building structures. So it is necessary to study the effect of various industrial effluents on soil properties. In this paper, an attempt is made to study the effect of textile effluent on clayey soil. Textile effluent is added in varying percentages from 25 to 100% with an increment of 25% to study the effect on plasticity index, pH and unconfined compressive strength.
Key Words: Textile effluent, Plasticity index, OMC, MDD, UCC, pH.
1.INTRODUCTION
2. MATERIALS AND METHODS
Textile Industry is one of the growing industries in our country. The effluent released by this industry is deposited on river and land areas. Many researchers have suggested that textile effluent can cause river pollution and thereby affecting the balance of the environment. But the effluent deposited on land may add some benefits to the soil properties. If so, then it is beneficial and supports the stability of the structures. But it is necessary to study the interaction between the soil and the industrial effluent. Hence in this study, an attempt is made to study the interaction between textile effluent and high plastic clay. Textile effluent is added in varying concentrations from 0 to 100% with an increment of 25%. A lot of research works have been carried out on expansive soils to study the effect of textile effluent. Vaadi, et al., (2015) studied the effect of textile effluent on geotechnical properties of expansive soil. They have observed an increase in compressive strength due to the textile effluent. Rao, et al., (2009), studied the effect of textile effluent on geotechnical properties of black cotton soil. The result was decrease in differential free swell index. Similar works were done by so many researchers and they have suggested that textile effluent can minimize the problems in an expansive soil. Ayush, et al., (2010), studied the interaction of silty soil with textile dye. They observed an increase in optimum moisture content and unconfined compressive strength. Similar works were conducted by so many researchers and most of them observed an improvement in soil properties. Š 2017, IRJET

With respect to both the quantity and composition, the textile processing wastewater is recorded as the most polluted sources among all industrial sectors.The bulk effluents generated from textile industries are discharged either treated or untreated over the soil leading to changes in soil properties causing improvement or degradation of engineering behavior of soil. If there is an improvement in engineering behavior of soil, there is a value addition to the industrial wastes serving the three benefits of safe disposal of effluent, using as a stabilizer and return of income on it. The change in geotechnical properties due to effluent contamination must be studied before any construction work is started. Otherwise it may cause problems to geotechnical engineer. Textile effluent interaction with high plastic clayey soil is discussed here.
