However, stress-strain and pore pressure response of lime-Treated fly ash under a saturated state has not been explored. In this study, shear strength, pore water pressure response, and durability of lime-Treated class-F fly ash have been evaluated. Unconfined compressive strength of lime-Treated fly ash was determined for different curing time periods (7-84 days). A series of consolidated undrained (CU) triaxial tests were performed, and a new procedure for saturation of lime-Treated specimens was developed to ensure its B (saturation value) to be 0.95. This study was further extended to conduct the durability analysis for two cases: soaking under water and wetting-drying cycles. Lime-Treated specimens exhibited improved strength and durability response. In addition, lime-Treated specimens under saturated state showed higher dilative behavior and brittle response than untreated fly ash. � 2023 Elsevier B.V., All rights reserved.EnglishCompressive strengthCuringDurabilityFly ashPore pressureWater treatmentWettingExcess pore water pressureFill materialsGeotechnical applicationLime treatmentPressure responseSaturated stateShears strengthSoakingWater durabilityWetting-dryingLimeConference paper20230
