STABILIZATION OF EXPANSIVE SOIL WITH EGG SHELL POWDER AND QUARRY DUST

Abstract

Soil plays an important role for many construction works especially for dams, bridges and canals.  The presence of clay minerals exhibit alternate swelling & shrinkage depends upon the seasonal variations.  Large numbers of researches are being carried out throughout the world to improve the soil quality. Various laboratory investigations were carried out for utilizing Egg Shell Powder (ESP) and Quarry Dust (QD) as a stabilizing agent to improve physical and mechanical properties of soil.  To utilize the waste product to the corrected material for construction works and doesn’t affect the environmental aspect also.  Stabilization of soil with lime, cement, bitumen are expensive and therefore in need of an economic replacement.  Soil taken with various ratios by addition of  which 4% of ESP and without ESP followed by the increment of 5% of QD through moisture-density relationship at Standard Proctor Compaction test, California Bearing Ratio (CBR) at soaked condition, Consistency limits, Unified Compressive strength (UCS) test and  Swell Pressure Test were carried out . The purpose of the study is to use of QD and ESP and evaluate the optimum combination to increase soil stabilization, geotechnical properties, reduce plasticity index and provide a solution for land filling, pavement structure and also for environmental problem.
