Soil Stabilization by Using Lime and Fly Ash

For any type of structure, the foundation is very important and it has to be strong to support the entire structure. In order for the strong foundation, the soil around it plays a very critical role. To work on soils, we need to have proper knowledge about their properties and factors which affect their behaviour. By consolidating under load and changing volumetrically along with seasonal moisture variation, these problems are manifested through swelling, shrinkage and unequal settlement. In this paper the experimental results obtained in the laboratory on expansive soils treated with industrial waste fly ash and lime are presented. A study is carried out to check the improvements in the properties of expansive soil with fly ash and lime in varying percentages. The test results such as liquid limit, standard proctor and differential free swelling test obtained on expansive clays mixed at different proportions of lime and fly ash admixture are presented and discussed in this paper. The results show that the stabilized clay has lesser swelling potential whereas an increase in optimum moisture content has been observed. P. Bala Krishana | G.
