Experimental Investigation On The Synergistic Stabilization Of Expansive Soil Using Calcium Chloride And Shredded Rubber Mulch

Abstract

Expansive Soils, Commonly Referred To As Black Cotton Soils In India, Present Significant Geotechnical Challenges Because They Undergo Swelling When They Absorb Moisture And Shrink Upon Drying. This Repeated Cycle Of Expansion And Contraction Can Lead To Considerable Damage To The Foundations Of Structures Constructed On Such Soils. Therefore, Understanding The Engineering Behaviour Of Expansive Soils And Implementing Suitable Stabilization Techniques Has Become An Important Area Of Study For Geotechnical Engineers. Considerable Research Has Been Undertaken To Identify Effective Methods For Minimizing The Expansive Characteristics Of These Soils. Among The Various Ground Improvement Techniques, The Use Of Electrolytes Has Emerged As A Promising Approach For Enhancing The Engineering Properties Of Expansive Soils. In The Present Study, A Systematic Laboratory Investigation Was Carried Out To Evaluate The Effects Of An Electrolyte And An Industrial Waste By-product, Namely Shredded Rubber Mulch, Together With Calcium Chloride, On The Engineering Properties Of Expansive Soil. The Experimental Program Was Conducted Under Carefully Controlled Laboratory Conditions Following A Structured Testing Methodology To Assess The Effectiveness Of These Stabilizing Materials.
