Laboratory Investigation of Soil Stabilization Using Terrazyme and Cement

The process of enhancing soil engineering properties is known as soil stabilization. The problematic soils can be improved by adding bio-enzymes and cement. In the present examination, a bio-enzyme named terrazyme is utilized. Terrazyme is a liquid enzyme that is non-toxic and all-natural plant fermentation in its production; hence, it is adopted to investigate the effect of stabilized performance in road construction. The main objective of the study was to identify the optimum dosage of terrazyme-stabilized soil with cement. The dosage of cement was added in percentages of 3, 3.5, 4, 4.5, and 5% by the dry weight of soils. An analysis of the physical and mechanical properties of the soil was analysed by using the CBR test and UCS tests. For 7, 14 and 28 days, the samples were evaluated and cured, respectively. The results were found to be that the optimum dosage of 4.5% along with cement gave maximum strength for terrazyme 5x chemical, 5% along with cement gave maximum strength for terrazyme 11x chemical, and hence bio-enzymes chemical like terrazyme can be used for soil stabilization in problematic soil.
