Stabilization of Expansive Soil Using Terrazyme
The black cotton soil is an expansive soil having a high potential for shrinking and swelling with seasonal moisture variations due to which black cotton soil fails to bear imposed load. Thus, stabilization of black cotton soil is one of the challenging tasks for engineers. The stabilizers used must be economical, easy to implement, and eco-friendly but the methods used conventionally were time-consuming and uneconomical. It is better to use terrazyme to stabilize a soil as it is natural, non-toxic, inflammable, non-corrosive, biodegradable liquid enzyme formulated from fermented vegetable extracts and it shows a permanent effect. This paper deals with a series of tests conducted on virgin soil as well as the tests conducted on the terrazyme treated soil with different dosages such as 0.5/075/1/1.5 cubic meters of soil per 200 ml terrazyme. Adding terrazyme shows significant improvement in engineering properties of soil such as specific gravity, consistency limits, optimum moisture content, maximum dry density, unconfined compressive strength, swelling index, and California Bearing Ratio (CBR) (soaked). On the basis of these results, the optimum dosage is obtained. Apart from this, the soil which we are used must have at least 10% of clay content for the effect of terrazyme.
