Abstract

Soft clay soils, characterized by their low shear strength and high compressibility, pose significant challenges in construction and civil engineering. Traditional stabilization methods often involve high costs and environmental impacts. This study explores the use of eggshell lime and rice husk ash as sustainable alternatives for enhancing the resilience of soft clay grounds. Eggshells, when processed into lime, and rice husk ash, a by-product of rice milling, exhibit pozzolanic properties that improve soil strength and durability. The combined use of these materials results in enhanced soil stabilization through increased compressive strength, reduced plasticity, and improved resistance to moisture variation. This method not only offers an eco-friendly solution but also reduces construction costs by utilizing readily available, low-cost materials. Field applications demonstrate the practical benefits of this approach, making it a promising technique for sustainable soil improvement in various construction contexts.
