Improvement in Geotechnical Properties of Clayey Soil by use of Rice Husk Ash and Alccofine 1101
Journal Title: International Invention of Scientific Journal - Year 2018, Vol 2, Issue 7
Abstract
Natural The potential of using rice husk ash (RHA) and alccofine 1101 in stabilization of clayey soil is evaluated in this study. The combined use of these two materials to form a binder provides new opportunities to enhance engineering characteristics of expansive clays. The results revealed that maximum decrease in the liquid limit (40.20%) was observed at 10% rice husk ash and 5% alccofine. The plastic limit of the clayey soil has been improved by 24.31% to 34.90% on addition of rice husk ash from 0% to 10% and alccofine from 0 to 5%. The plasticity index of the clayey soil has been decreased by 26.09% to 5.30% on addition of rice husk ash from 0% to 10% and alccofine from 0 to 5%. It is found that the MDD decreased from 1.49 g/cm3 to 1.29 g/cm3 of the clayey soil on addition of rice husk ash from 0% to 10% and alccofine from 0 to 5%. However, increasing the concentration of alccofine 1101in mixes increased the MDD values than mixes with RHA alone. The results concluded that increasing percentages of rice husk ash and alccofine added for stabilization of clayey soil enhances its strength.
