20.500.12556/DiRROS-16240 Impact of leaching on chloride ingress profiles in concrete To investigate the effect of leaching on chloride ingress profiles in concrete and mortar, we exposed concrete and mortar specimens for 90 and 180 days to two different exposure solutions: 3% NaCl, and 3% NaCl with KOH added to limit leaching. The solutions were replaced weekly. After exposure, we determined total chloride profiles to investigate the chloride ingress, and portlandite profiles to assess the extent of leaching. The results showed that leaching during exposure greatly affects the chloride ingress profiles in mortar and concrete. We found that leaching leads to considerably higher maximum total chloride content and deeper chloride penetration into the concrete than in the specimens where leaching was limited. We recommend therefore that leaching should be taken into account in standard laboratory testing and that more mechanistic service life models should be used to take into account the impact of leaching. chloride ingress service life prediction leaching concrete portlandite open access prodor kloridov napoved življenjske dobe izcejanje beton portland odprti dostop true false true Springer Netherlands Angleški jezik Slovenski jezik © The Author(s) 2021 Neznano 2023-02-10 07:55:02 2023-05-04 10:33:00 2023-05-05 03:35:30 0000-00-00 00:00:00 2022 0 0 Nasl. z nasl. zaslona; Opis vira z dne: 31. 1. 2023; str. 16-18 iss. 1, article no. 8 Vol. 55 Jan. 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2021-12-23 620.1/.2 1871-6873 10.1617/s11527-021-01730-w 140192515 RAZ_Machner_Alisa_2022.pdf RAZ_Machner_Alisa_2022.pdf 1 B16EC12A5424C5A783DF2138CEFFE269 0509c77fc6ee30c51c75915f4fa13c9710868c04d4ae6f88cf62be6eebefb2d5 aad026cd-a910-11ed-b359-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=21643 RAZ_Machner_Alisa_2022.pdf RAZ_Machner_Alisa_2022.pdf 1 7FB6C0BD688A7EDDC2457CADCB884BAA 001d92af1e978ea2d8567d6626849f2c80d636751e28c4c4e198e54069a315ab 7b767b05-ea45-11ed-a314-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=22255 https://link.springer.com/article/10.1617/s11527-021-01730-w 0 8129fbf4-ea45-11ed-a314-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=22256 Zavod za gradbeništvo Slovenije 0 0 0
