20.500.12556/DiRROS-25227 Opening letter of RILEM TC CS Calcium sulfoaluminate-based cement and concrete – critical review and open questions Calcium sulfoaluminate (CSA)-based cements represent a promising alternative to traditional Portland cement, offering benefits such as rapid strength development, low shrinkage, and reduced carbon footprint. Despite their commercial availability and proven performance, the adoption of CSA cements remains hindered by gaps in standardization and understanding. This RILEM Technical Committee (TC) CSA aims to review current knowledge, identify research needs, and address challenges related to clinkering, hydration mechanisms, durability, applications, nomenclature, standardization, and testing of CSA-based cements. The outcomes will further the understanding of manufacturing, technical performance, use, and specification of CSA-based cements, ultimately leading to broader acceptance in concrete construction. calcium sulfoaluminate cement ye'elimite belite ettringite low-CO2 cement kalcijevo-sulfoaluminatni cement yelimit belit etringit nizkoogljični cement true false true RILEM Publications SARL Angleški jezik Slovenski jezik © The Author(s) 2025 Neznano 2026-01-14 08:08:51 2026-01-14 08:14:02 2026-01-15 03:48:45 0000-00-00 00:00:00 2025 0 0 str. 106-118 Vol. 10 18. 12. 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2025-12-18 620.1/.2 2518-0231 10.21809/rilemtechlett.2025.231 263233027 https://doi.org/10.21809/rilemtechlett.2025.231 0 e4fbbdaa-f117-11f0-94a7-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=38055 RAZ_Bescher_Eric_2025.pdf RAZ_Bescher_Eric_2025.pdf 1 66B3574FF568992818E246B863743D5F f0c4e0bada057105e7ee193d7f54a517b8ea32152ad7f8ed2dfbfcf07f9346a0 76cf02cf-f118-11f0-94a7-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=38058 Zavod za gradbeništvo Slovenije 0 0 0
