Effects of Bio-enzyme in Soil Stabilization

The bioaugmentation approach of soil strength enhancement is one of the most efficient and sustainable methods for enhancing soil engineering properties. One of the methods is by using bio-enzymes. Bio-enzymes are organic soil improvement additives which are non-toxic, environmentally friendly, and biodegradable. With this view, the major objective of the current study is to study the effectiveness of bio-enzyme on UCS and swelling properties of soil. For the experimentation, the fractional factorial planning method has been adopted with the target to maximize the UCS of soil with the factors and levels considered. Scanning electron microscope (SEM) analyses were conducted at the end of each UCS test. The results obtained indicate an increase in UCS soil and a reduction in swelling of soil. It was observed from the results of SEM that with the increase in curing period soil specimens are denser. Also, the optimum value of dosage of TerraZyme was found for defined outcomes.
