GEOTECHNICAL MODIFICATION AND CHEMICAL ANALYSIS OF EXPANSIVE SOILS

  • Chelimalla Sagar et. al

Abstract

This paper reports an investigation of the impact of pyroclastic rock dust on the geotechnical properties of expansive soil. The versatility, direct shrinkage, compaction, California bearing proportion (CBR) and shear quality attributes of the soil when blended in with changing extents of pyroclastic rock dust were examined. The results show noteworthy decrease in versatility and direct shrinkage of expansive soil with expanding measure of pyroclastic rock dust. The most extreme dry thickness, ideal water content, shear quality and CBR all expanded with expanding pyroclastic rock dust content. Ideal CBR esteems were acquired with the expansion of up to 8% pyroclastic rock dust. The conduct of the geotechnical properties of the expansive soil when mixed with pyroclastic rock dust demonstrates that the stone residue is a decent modifier for this issue soil.
