Compaction behavior of clayey soils treated with lime by-products

Understanding the intricate relationship between lime treatment, soil characteristics, compaction behavior, and curing time is crucial for achieving desired soil density and compaction properties. This study investigates the impact of lime by-product treatment on clayey soils and reveals that the combined influence of mineralogy, chemical components, and dosage determines the effectiveness of the cation exchange reaction, resulting in shifts in optimal compaction points along specific saturation curves. The time before compaction significantly affects soil density and lime treatment efficiency. Excessive delay in compaction compromises cementation, emphasizing the importance of optimal compaction time which is around two to three hours. The compaction curves offer insights into the required lime saturation level for effective cation exchange. These findings, along with other highlighted aspects in the article, have practical implications for soil stabilization and lime by-product treatment, providing guidance to engineers and researchers in optimizing lime application in clayey soil applications.
