Stabilization of Clayey Soil Using Mineral Additives

EasyChair Preprint no. 12985

Abstract

Soil improvement is a process aimed at enhancing resilience &strength of soil. This involves modifying characteristics of less stable soil to enhance its compressive strength or modifying properties of foundation soil to ensure their suitability. By augmenting shear strength & managing soil shrink-swell behaviour, it elevates ability of a subgrade to uphold pavements & foundations.Fortified soil ameliorates tensile strength, bearing capacity, & overall soil performance. Procedure of soil stabilization involves utilization of various chemicals. Among prominent approaches for enhancing engineering attributes of problematic soil is chemical stabilization. In contemporary era, lime has emerged as a popular chemical stabilizer. Given current scenario of depleting resources & energy consumption, there is a growing inclination towards utilizing waste materials as soil stabilizers. Sugarcane bagasse ash, a silica-enriched byproduct obtained from incineration of sugarcane , is one such material. Main objective is to compare stabilizing effectiveness of lime, bagasse ash(BA) & Granulated Blast Furnace Slag( GBFS). Percentage of lime used is 4%,8%,12%.BA)& GBFS is used in 6%,12%, 18% and 9%,18% & 27% respectively.Laboratory investigations were conducted to assess impact of varying proportions of lime, BA, & GBFS on stabilization of clayey soil. Findings indicate that this stabilization technique can substantially enhance the geotechnical attributes of clayey soil, offering practical &enduring solutions for construction endeavours.

Keyphrases: Bagasse Ash (BA), California Bearing Ratio (CBR), Granulated Blast Furnace Slag (GBFS), Optimum Moisture Content (OMC)
