ABSTRACT |
Influence of industrial effluents on soil, water, and air has been the subject matter of several researchers. This investigation aims at studying the influence of spent orange dye effluent from a Textile industry on a clayey soil. The soil is mixed with spent orange dye effluent and tested for Index properties and Engineering properties after varying curing periods. Influence of each component of dye effluent on soil is ascertained by another series of tests by mixing it with soil. The dye effluent and its constituents are found to induce cementation/bonding and flocculation to the soil resulting in improved engineering properties. X – Ray diffraction studies reveal that the clay minerals present in the soil react actively with dye effluent. The observed changes are explained in terms of changes brought out in chemical environment of pore fluid, pH and physico – chemical interactions between soil particles and particle groups.
Keywords: Consolidation, Swelling, Atterberg limits, textile dye effluent.
