156 Figure 11- Nitrogen adsorption−desorption BET isotherm of sample S, SC, and SCD (Khan & Shrive, 2026a) Figure 12- The soil-water characteristic curve of S, SC, and SCD compacted samples (Khan & Shrive, 2026a) Improved durability Khan & Shrive (2026b) evaluated the influence of Duraflex admixture on the durability performance of cement-stabilized soils under severe environmental conditions, specifically freeze-thaw (F-–T) (Figure 13) and wetting-drying (W-–D) (Figure 14) cycles. The results demonstrate that incorporation of DFI significantly enhances resistance to strength degradation and mass loss under repeated environmental cycling compared with cement-only stabilization.
