Strengthening of Soil Subgrade Using Bio-Enzyme

Shil, T. / Pradhan, R. / Nanda, Satyajeet / Mohapatra, Benu Gopal

Soil stabilization is frequently used in construction. In recent years, bio-enzyme base soil stabilization has been promoted by various enzyme manufacturers. These manufacturers are claiming the high increase in soil shear strength, reduction in soil liquid limits, and swelling properties. In this paper, a review as well as experimental study was carried out on the use of bio-enzyme in soil stabilization. Various studies suggest the use of bio-enzyme and indeed increase the soil shear strength properties up to 35% for clay. The strength gaining of bio-enzyme treated soil is very slow. Few other studies suggest that bio-enzyme not increases enough shear strength and it may not be useable to all kind of clay minerals.
