Durability of Cementitious Materials in Arctic Regions: Investigating Freeze-Thaw Damage and Chloride Ingress Diffusion Mechanisms
… durability challenges from freeze-thaw (F-T) cycles and chloride ingress due to seawater and deicing salts, resulting in surface scaling, spalling, and cracking. Climate change exacerbates these issues, particularly in high-latitude areas like Alaska, where rising temperatures lead to …

Evaluation of Moisture, Suction Effects and Durability Performance of Lime Stabilized Clayey Subgrade Soils
… after subjected to 10 and 20 freeze-thaw (F-T) cycles in a controlled environmental chamber. MR and UCS results of F-T samples are compared with no F-T damage samples. It is seen that resilient modulus values of untreated soils reduces significantly (>80%) after 20 F-T cycles. Lime stabilization …

Impact of Anti-Strip Additives on Performance of Asphalt Pavements
… dynamic modulus and multiple freeze-thaw (F-T) cycles.* Resistance to permanent deformation: relationship between permanent strain in the HMA mix and number of load repetitions under triaxial testing conditions at the un-conditioned and moisture-conditioned stages.The resistance of the mixtures …

The effects of chloride-based deicing chemicals on degradation of portland cement mortars with alkali reactive aggregate
… exposure to deicers, freezing and thawing cycles, and wetting and drying cycles. In order to develop a more comprehensive view of these topics, the present study was conducted in three phases. The focus of the first phase was on studying the effects of the chloride-based deicers on the …

SYNTHESIS AND CHARACTERIZATION OF NEW ELECTROCATALYTIC MATERIALS TO IMPROVE THE PERFORMANCE, OPERABILITY AND LIFE-TIME OF PEMFCS
… them to various freezing/ thawing (F/ T) cycles: both electrochemical performance and mechanical stresses are considered, in order to verify the effectiveness of the dehydration processes in avoiding cracks and maintaining thus a satisfactory FC performance (limited decay of the …

Durability of cement and concrete matrices incorporating nanocellulose fibers (NCF)
… mélanges de mortier à travers divers tests et cycles de mouillage-séchage. Les résultats ont montré la résistance des NFC à l'attaque des ions alcalins et leur efficacité à améliorer des propriétés du mortier, en particulier dans les systèmes ternaires. Cependant, au-delà de 20 cycles de …
