STABILIZATION OF BLACK COTTON SOIL USING BIO-ENZYMES
Abstract
Bio-enzymes are fermented vegetable extracts which improves the engineering qualities of soil, provides high soil compaction densities. It also increases the stability. Bio-enzymes are natural, non-toxic and non-corrosive liquid. The reaction between the clay particles and ions are catalysed by the bio-enzymes. The absorbed double layer thickness is reduced by the bio-enzymes. While chemicals are added to soil it is difficult to mix. But bio-enzymes can be easily mixed with soil and compacted. A study is carried out to check the improvements in the properties of black cotton soil with bio-enzymes in varying dosages as 1ml/kg, 2ml/kg, 3ml/kg, 4ml/kg, 5ml/kg. In this study soil properties at normal conditions are tested and soil properties after stabilization with varying dosages were evaluated. The test such as CBR and UCC are carried out. The result indicates that the bio-enzymes increase strength to a greater extent, thus bearing capacity increases in stabilized soil.
