Various quantities of cement and RHA were incorporated into the peat soil in the laboratory; cement was introduced in proportions of 5% to 15%, while RHA was added in amounts of 6%, 8%, and 12% depending on the weight of the soil. The dry density increases with an increase in cement content, while the optimal water content decreases. Conversely, as the RHA level increases, the optimum moisture content (OMC) increases, but the maximum dry density (MDD) reduces. Microstructural analytical tools such as FESEM and XRD facilitated an extensive analysis of the cement-peat-RHA reaction. Unconfined compressive strength (UCS) tests were carried out on the samples after 0, 7, 14, and 28 days of curing to evaluate their strength behavior.
