Results indicate that under water and NaCl conditions, no significant mass loss or modulus reduction occurred, with only minor surface efflorescence. However, in the composite solution, severe spalling was observed, with mass loss reaching approximately 1.4% and the relative dynamic modulus decreasing to around 90% after 540 days. Dry\u2013wet cycling accelerated the corrosion process compared to immersion, leading to greater mass loss and modulus reduction. The incorporation of slag improved resistance to ionic penetration in both chemical corrosion and salt crystallization, though this effect diminished with prolonged exposure or increased cycling.<\/jats:p>","DOI":"10.3390\/ma18091931","type":"journal-article","created":{"date-parts":[[2025,4,24]],"date-time":"2025-04-24T06:18:02Z","timestamp":1745475482000},"page":"1931","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Study on Mass and Performance Deterioration of Concrete Under Multiple Corrosive Environments"],"prefix":"10.3390","volume":"18","author":[{"given":"Haicheng","family":"Yang","sequence":"first","affiliation":[{"name":"CCCC Fourth Harbor Engineering Institute Co., Ltd., Guangzhou 510230, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Weifeng","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Civil and Airport Engineering, Civil Aviation College, Nanjing University of Aeronautics and Astronautics, Nanjing 210016, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hongfa","family":"Yu","sequence":"additional","affiliation":[{"name":"Department of Civil and Airport Engineering, Civil Aviation College, Nanjing University of Aeronautics and Astronautics, Nanjing 210016, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wei","family":"Wang","sequence":"additional","affiliation":[{"name":"CCCC Fourth Harbor Engineering Institute Co., Ltd., Guangzhou 510230, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Haiyan","family":"Ma","sequence":"additional","affiliation":[{"name":"Department of Civil and Airport Engineering, Civil Aviation College, Nanjing University of Aeronautics and Astronautics, Nanjing 210016, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,4,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"105041","DOI":"10.1016\/j.cemconcomp.2023.105041","article-title":"Durability of concrete coupled with life cycle assessment: Review and perspective","volume":"139","author":"Li","year":"2023","journal-title":"Cem.
