Bio-enzyme Stabilization Of Expansive Soils Sustainable And Eco-friendly Alternative To Lime/cement

Abstract

Expansive Soils, Particularly Black Cotton Soils, Exhibit Significant Swelling And Shrinkage Behavior Due To Moisture Variation, Causing Structural Instability And Damage To Infrastructure. Traditional Stabilization Techniques Using Lime And Cement, Although Effective, Are Associated With High Carbon Emissions And Environmental Degradation. This Research Paper Explores Bio-enzyme Stabilization As A Sustainable And Eco-friendly Alternative. Bio-enzymes, Derived From Organic Fermentation, Improve Soil Properties Through Catalytic Reactions That Enhance Particle Bonding And Reduce Water Affinity. This Study Reviews Mechanisms, Experimental Findings, Advantages, Limitations, And Field Applications Of Bio-enzyme Stabilization. Results Indicate Substantial Improvements In Strength, Reduction In Plasticity, And Enhanced Durability, Making Bio-enzymes A Promising Alternative For Sustainable Geotechnical Engineering
