20.500.12556/DiRROS-23712 Characteristics of lightweight aggregate concrete interfacial transition zone Karakteristike tranzitne zone betona na bazi lakog agregata The paper presents the characteristics of the interfacial zone between the lightweight aggregate produced on the basis of waste materials and binder matrix with the application of the methods SEM, EDS and the Vickers micro hardness test. On the basis of the SEM and EDS analysis, as well as the criteria for the atomic ratio of elements which compose some products of hydration, we can gain insight into the dominant composition of the interfacial zone. The values of the Vickers micro hardness test for four kinds of tested concrete after seven days of hydration is impossible to correlate with the composition of the interfacial zone in reliable way, whereas after twenty eight days the differences in values are insignificant. U radu je prikazana karakterizacija tranzitne zone između zrna lakog agregata proizvedenih na bazi otpadnih materijala i vezivnog kamena pomoću metoda SEM, EDS i određivanjem Vikersove tvrdoće. Na bazi SEM i EDS analize, kao i kriterijuma za odnose atoma elemenata koji ulaze u sastav nekih produkata hidratacije, može se dobiti uvid u preovlađujući sastav tranzitne zone. Vrednosti Vikersove tvrdoće za četiri vrste ispitanih betona se nakon sedam dana hidratacije nije moguće povezati sa gustinom pakovanja čestica veziva u tranzitnoj zoni sa velikom sigurnošću, a nakon dvadeset osam dana razlike u vrednostima nisu značajne. lightweight aggregate waste material interfacial zone lahki agregat lahki beton odpadni material tranzicijska cona true false true Society for Materials and Structures Testing of Serbia = Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije Angleški jezik Srbski jezik (cirilica) Neznano 2025-09-26 10:26:52 2025-09-26 10:34:31 2025-10-24 03:54:54 0000-00-00 00:00:00 2014 0 0 str. 63-77 br. 3 God. 57 2014 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2014-08-06 624 2217-8139 2056807 https://doi.org/10.5937/grmk1403063M 0 8eebbac3-9ab2-11f0-9bb7-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=35137 RAZ_Milovanovic_Vesna_2014.pdf RAZ_Milovanovic_Vesna_2014.pdf 1 737D9641D6E4E9F9BE0B70BB17705D7B 81691589c6f5aaf2724bc5d0180b7e0b14035ea4f44ae5627acc002fc5943234 7e36f548-9ab3-11f0-9bb7-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=35138 Zavod za gradbeništvo Slovenije 0 0 0
