20.500.12556/RUL-185617 Modeling the physical properties of mortar with the application of expanded vermiculite This paper presents a laboratory study on the physical properties of mortar incorporating expanded vermiculite. The basic cement-lime mortar matrix remained unchanged, while the proportions of vermiculite were varied at 10%, 20%, and 30%. The research results demonstrated a significant improvement in physical properties, including compressive and flexural strength, as well as the static modulus of elasticity. This study establishes relationships between these properties and examines the impact of expanded vermiculite on characteristics such as air void content, capillary suction of hardened mortar, total porosity (according to SIA 262, Appendix A), gas and air permeability, and capillary water absorption. Additionally, the water permeability of the mortar was tested, along with its internal resistance to freeze-thaw cycles, up to 200 cycles. The findings of this laboratory research contribute to filling an existing scientific gap, demonstrating that the physical properties of mortar with the addition of expanded vermiculite at 10%, 20%, and 30% are significantly improved compared to mortar without vermiculite. lightweight cement-lime mortar expanded vermiculite laboratory investigations lahka cementno-apnena malta ekspandiran vermikulit laboratorijske preiskave true false true Angleški jezik Srbski jezik (cirilica) Članek v reviji 2026-08-13 10:30:32 2026-08-13 10:30:39 2026-08-14 04:03:55 0000-00-00 00:00:00 2026 0 0 Str. 231-250 issue 2 Vol. 58 2026 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 691:666.97 0350-820X 10.2298/SOS250204015S 237485571 Stustersic...-Modeling_the_Physical_Properties_of_Mortar_with_the_Application.pdf Stustersic...-Modeling_the_Physical_Properties_of_Mortar_with_the_Application.pdf 1 864D52D6BFFE2B6F2DBE4BD4C22C508C 0b191a9ece130006e5cef71e4d9c790f60b7a0f3ffbc85b608e4e8f7ef9cd6de 01cbd30d-96f1-11f1-9b0d-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=244332 https://doiserbia.nb.rs/Article.aspx?ID=0350-820X2500015S 1 ec29a3f6-96f0-11f1-9b0d-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=244331 Fakulteta za gradbeništvo in geodezijo 0 0 0
