Treatment of Collapsible Soils with Granulated Blast Furnace Slag and Calcined Eggshell Waste

Abstract In order to meet environmental and socio-economic challenges, the recycling of waste be used in treatment geotechnical problems is one main ways preserving environment with a lower economic value. The objective this experimental work improve characteristics study mechanical behaviour collapsible soil treated new hydraulic stabilizer composed Crushed Granulated Blast Furnace Slag (CGBS) active by Eggshell Waste (CES). specimens were mixed content, varying from 0 15% mass, an initial water content 4, 6 8% respectively. mass. Oedometer apparatus was addition effect on Collapse Potential. Triaxial tests are also conducted determine shear strength parameters (cohesion internal friction angle) soil. results research show that properties significantly improved. An appreciable reduction collapse potential observed. 4% under compaction 60 blows/layer capable increasing angle cohesion. It can concluded mixture granulated slag calcined eggshell as effective collapsibility phenomenon at low cost while protecting industrial waste.
