STUDY OF STRESS-STRAIN BEHAVIOUR OF COHESIVE SOILS MIXED WITH GRANITE DUST UNDER TRIAXIAL TEST
Abstract
This research study explores the application of granite dust as a soil stabilizer. Thestudy investigates the effectiveness of utilizing granite dust to improve the engineeringproperties of soil, particularly in terms of stability and strength.The impact of granite dust on the behavior of the soil subjected to loading wascritically considered in this study. Soils blended with several amounts of granitepowder at percentages of 25%, 35%, 45%, and 55% of the total weight of the soilwere examined. The index properties, compaction and triaxial tests were executed toevaluate the performance of both the treated and untreated samples.The result from the specific gravity test shows that theres an increase in the specificgravity of the natural soil sample when granite dust is added to it at varying percentages.The result from the Atterberg limit test shows that there is a decrease in the liquid limitof the soil and a corresponding decrease in the plastic limit of the soil due to the increasein the granite dust proportion. The result of the compaction test carried out shows thatthe dry density of the soil increases with addition of granite dust at varying percentages.The triaxial test analysis shows that there is an improvement in the strength propertiesof the soil as a result of an increase in the cell pressure with an increase in the granitedust proportion.The results emphasized that granite dust has the potential to be a practical andsustainable choice for soil stabilization, demonstrating positive impacts on soilcohesion, compaction, and shear strength. This study offers valuable insights forconstruction professionals, indicating the feasibility of integrating granite dust as a soilstabilizer in diverse civil engineering endeavours.
