20.500.12556/DiRROS-24128 Test methods for chloride diffusivity of blended cement pastes a review by RILEM TC 298-EBD The use of supplementary cementitious materials (SCM) is an important part of the roadmap for reducing CO2 emissions and extending the service life of reinforced concrete structures. To accelerate the adoption of SCMs, the RILEM Technical Committee 298-EBD evaluates scaled-down cement paste test methods to assess the effect of SCM on resistance to chloride and sulfate ingress and reactivity, which are critical to concrete durability. This review focuses on methods for measuring chloride diffusivity and is divided into four sections: diffusivity models and parameters, diffusion test methods (including NMR and chloride measurements), migration test methods and implications for future research. Key insights highlight the complexities of multi-species ionic and molecular diffusion/migration, including various binding interactions, and compares the different measurement methodologies. The review also addresses the test scale and aggregate effects, noting the pros and cons of testing at the paste, mortar, and concrete scales. The review underscores the need for further investigation into testing protocols and the influence of SCM on chloride diffusion, emphasizing that comprehensive testing across different scales provides complementary information for assessing durability performance. cements chloride SCMs cement kloridi mineralni dodatki true false true Springer Netherlands Angleški jezik Slovenski jezik © The Author(s) 2025 Neznano 2025-11-17 09:42:21 2025-11-17 09:47:20 2025-11-18 03:43:31 0000-00-00 00:00:00 2025 0 0 str. 1-35 article no. 324 Vol. 58 Nov. 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2025-11-04 620.1/.2 1871-6873 10.1617/s11527-025-02809-4 256233987 https://doi.org/10.1617/s11527-025-02809-4 0 573458bc-c391-11f0-94a7-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=35898 RAZ_Ukrainczyk_Neven_2025.pdf RAZ_Ukrainczyk_Neven_2025.pdf 1 31149819B6733EE0028A3DA9E904801A ce59600f0dabe17ec09dda97c9374d1368b52c13ef972482e1bfc452a416c7ff fa38bb9d-c391-11f0-94a7-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=35899 Zavod za gradbeništvo Slovenije 0 0 0
