Modification of the Geotechnical Properties of Loess Using Eggshell Waste (El'Mghair Region)

Abstract

Soil stabilization with eggshell waste is an important aspect of sustainable engineering and environmental management. It offers a cost-effective and environmentally friendly solution for improving the physical and mechanical properties of soils. This study investigates the transformative impact of eggshell as a soil treatment agent on loess soil (EM). Various tests, including Proctor, collapse potential, Atterberg limits, shear strength, and chemistry of the loess were conducted to assess the changes in soil properties with different eggshell content (0, 2, 4, 6, 8 and 10%). The results reveal that eggshell significantly affects soil compaction, stability, plasticity, and shear strength. Notably, the addition of eggshell, especially at 10% content, shows promise in enhancing soil properties, making it a potential candidate for soil stabilization and moisture management applications. However, the complex relationship between eggshell content and soil behavior underscores the need for further research to unlock its full engineering potential and optimize its application in treating loess soil. Overall, soil stabilization with eggshell waste provides a sustainable alternative to traditional stabilizers, contributing to the goal of environmentally friendly and cost-effective solutions in civil engineering.
