Abstract - The cost, performance, durability, and time of
friendly approach to soil stabilization, presenting a sustainable alternative to traditional chemical stabilizers. As we navigate through the literature, we will investigate the fundamental mechanism of terrazyme action, its influence on soil structure and the consequent enhancement in critical geotechnical parameters.
every project are its most crucial components. Black cotton soil, due to its strong swelling and shrinkage qualities, also known as expansive clay soil and regur soil, presents considerable difficulties in building and agriculture. Building on black cotton soil has its challenges, including foundation and road settlement, among others. Due to the shortcomings of conventional soil stabilizing technologies, new ways for enhancing the engineering properties of soil are being investigated. There is a demand for the creation of novel techniques to enhance the geotechnical properties of soil due to the inefficiency and high costs associated with conventional methods. Study examines the use of terrazyme, a state-of-the-art enzymatic soil stabilizer, to improve the geotechnical properties of black cotton soil, optimum moisture content, maximum dry density, liquid limit, plastic limit, plasticity index, and CBR test, which are used for pavement base courses, sub-base courses, and sub-grades. In this review paper, we mix the terrazyme at the rate of 200ml/2m3, 200ml/1.5m3, and 200ml/1m3 in black cotton soil to enhance the geotechnical properties of Black cotton soil.
1.1 Objective of the Study
Key Words: Black Cotton Soil, Terrazyme, CBR, liquid limit, plastic limit, plasticity index, optimum moisture content, maximum dry density.
Investigate the optimal dosages and treatment durations of the Terrazyme application, aiming to identify the most effective conditions for achieving desired improvements in geotechnical properties.
Terrazyme dosages to suit the specific characteristics of various subtypes within the black cotton soil category, recognizing that distinct variations may demand customized treatments to achieve optimal geotechnical improvements.
Mahesh C Swami et al. (2019) conducted a laboratory test and mainly focused on the plastic limit of Black cotton soil with various dosages of terrazyme like 0.25 ml, 0.50 ml, 0.75 ml. and 1ml per 100 ml of water. These dosages give favorable results regarding the geotechnical properties of soils which is useful in pavement construction including base courses, sub- base courses, and sub-grades.[2]
This review paper delves into the transformative journey of harnessing terrazyme for the enhancement of geotechnical properties in black cotton soil. Terrazyme, derived from microbial sources, brings a novel and eco-

Priyanka Vaishnava et al. (2015) conducted a study about the different dosages of terrazyme that were mixed with virgin soil (Dehradun) for various lengths of time. In this study, the result shows a noticeable improvement in the soil’s index properties, including specific gravity, maximum dry density, optimal moisture content, and California bearing ratio (both soaked and unsoaked).[1]
Black cotton soil, renowned for its unique composition and challenging geotechnical characteristics, has long posed a significant hurdle in construction and infrastructure development. The inherent expansiveness and high plasticity of this soil type often lead to substantial foundation problems, risking the stability and longevity of structures built upon it. In recent years, however, a groundbreaking solution has emerged in the form of terrazyme – A natural biotechnological catalyst that holds the promise to transform the geotechnical characteristics of black cotton soil.
