20.500.12556/DKUM-86924 Novel ultra-high-performance concrete (UHPC) enhanced by superhydrophobic and self-luminescent features This study explores the potential of using basalt reinforced UHPC by incorporating simultaneously self-cleaning and self-luminescent features, paving the way for sustainable advancements in civil engineering. New green formulations of UHPC were developed by integrating supplementary cementitious materials and optimizing water to the binder ratio, followed by using basalt fibers to enhance strength and ductility. The fabricated samples with high particle-packing density exhibit sufficient workability and compressive strength up to 136 MPa, and, when incorporating basalt fibers, a notable reduction in brittleness. The inner microstructure of basalt fibers was observed to be smooth, homogeneously distributed, and well adhered to the UHPC matrix. To ensure the desired long-lasting visual appearance of decorative UHPC and reduce future maintenance costs, a time-effective strategy for creating a light-emitting biomimetic surface design was introduced. The samples exhibit high surface roughness, characterized by micro to nano-scale voids, displaying superhydrophobicity with contact angles reaching up to 155.45°. This is accompanied by roll-off angles decreasing to 7.1°, highlighting their self-cleaning features. The self-luminescence feature showcased intense initial light emission, offering a potential energy-efficient nighttime lighting solutio UHPC basalt fibers mechanical properties morphology superhydrophobic self-luminescence mehanske lastnosti morfologija superhidrifobnost true false true MDPI Angleški jezik Slovenski jezik https://www.mdpi.com/2071-1050/16/3/1068 © 2024 by the authors Znanstveno delo 2024-01-29 13:46:17 2024-01-29 13:46:17 2025-07-02 10:35:21 0000-00-00 00:00:00 2024 0 0 21 str. iss. 3, [article no.] 1068 Vol. 16 Jan. 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2023-12-28 2024-01-22 2024-01-26 666 182880515 10.3390/su16031068 2071-1050 sustainability-16-01068.pdf sustainability-16-01068.pdf 1 BA5620ED75FB58CA786E43FF570B8098 59fc617ca4725412ffd59bea1859866506c49a099bab3a0a7d44c54f22850d0a 77077f93-bea4-11ee-aae6-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=175734 https://www.mdpi.com/2071-1050/16/3/1068 0 41b6ac75-f34b-11ef-a858-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=188809 Fakulteta za gradbeništvo, prometno inženirstvo in arhitekturo Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
