20.500.12556/RUL-168392 Effectiveness of prewetted fibres and aggregates in mitigating the autogenous shrinkage of high-strength concrete at an early age In this study, the influences of prewetted polypropylene fibres (PFs), basalt fibres (BFs), cellulose fibres (CFs), prewetted natural lightweight tuff aggregates (LTAs), artificial lightweight expanded clay aggregates (LECAs), and recycled brick aggregates (RBAs) on the early autogenous shrinkage and compressive strength of high-strength concrete (HSC) were investigated. Statistical analysis of variance (ANOVA) revealed a statistically significant difference between the reference concrete and some of the investigated concretes with prewetted materials. Among the prewetted fibres, PFs reduced autogenous shrinkage by 70% after one day and maintained the compressive strength at 96% after 28 days. Among the porous prewetted aggregates, LECAs (0–2 mm) were the most effective, reducing autogenous shrinkage by 97% and maintaining compressive strength at 107%. high strength concrete internal curing prewetted fibres prewetted aggregates compressive strength autogenous shrinkage statistical analysis beton visoke trdnosti notranje strjevanje predhodno namočena vlakna predhodno namočen agregat tlačna trdnost avtogeno krčenje statistična analiza true false true Angleški jezik Slovenski jezik Članek v reviji 2025-04-11 10:16:40 2025-04-11 10:16:43 2025-04-22 12:02:47 0000-00-00 00:00:00 2025 0 0 Str. 1029–1041 iss. 5 Vol. 23 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 69:539.4 1735-0522 10.1007/s40999-025-01079-z 226611459 s40999-025-01079-z.pdf s40999-025-01079-z.pdf 1 A89DA3C8AEC4309EDFE946AB450AE684 e167645edb79778a1380e3b28d2d95a1c644f58565923dcc093427cf9f28730c 95f0165b-16ac-11f0-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=201775 https://link.springer.com/article/10.1007/s40999-025-01079-z 1 35505676-16ac-11f0-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=201774 Fakulteta za gradbeništvo in geodezijo 0 0 0
