The influence of curing conditions before and after demolding on strength and durability was evaluated. Sealed curing at 80 °C for 24 hours enhanced C-A-S-H gel stability, improved early strength, and reduced drying shrinkage, but resulted in decreased long-term strength and sulfuric acid resistance. Conversely, sealed ambient curing promoted the development of a denser microstructure and higher long-term strength, albeit with increased drying shrinkage. The findings underscore the pivotal role of curing in optimizing the performance of VGP-based AAMs.</p>"}],"abstractLicenseFlag":"disallow"}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1410305278750800385","@type":"Researcher","foaf:name":[{"@language":"en","@value":"Sagawa
