A volume fraction of 1 vol. % basalt fibres was incorporated into the mixture, which significantly improved material ductility, reduced brittleness, and effectively bridged the generated cracks. SEM-EDS analysis confirmed the homogeneous distribution of fibers and their strong bonding with the hydration matrix. The developed mixture achieved a compressive strength of 138.5 MPa and a flexural strength of 12.5 MPa, which, despite the partial replacement of cement with metakaolin, confirms the very high mechanical performance of UHPC. To obtain additional multifunctional properties, such as pronounced water repellency and luminescent light emission, a double-layer biomimetic surface treatment based on SiO2 nanoparticles and luminescent powder was applied. Wettability tests demonstrated stable superhydrophobic behaviour with contact angles of up to 154.9°, while the luminescent layer enabled emission of visible green light at approximately 520 nm. The results confirm that the synergy of the optimized UHPC matrix, basalt fibres, and functional surface layers significantly expands the applicability of concrete, particularly in sustainably designed elements where crack control and water protection are crucial, while also providing passive nighttime visibility without an external energy source</dc:description><dc:description xml:lang="sl">Raziskava obravnava razvoj ultravisokozmogljivega betona (UHPC), zasnovanega na optimizirani cementni matriki z nizkim vodovezivnim razmerjem, doseženim z metodo mokrega zgoščanja delcev. V mešanico je bil dodan 1 vol.% bazaltnih vlaken, ki so bistveno izboljšala duktilnost materiala, zmanjšala njegovo krhkost ter učinkovito premoščala nastale razpoke. Analiza SEM-EDS je potrdila homogeno razporeditev vlaken in njihovo dobro vez s hidratacijsko matrico. Razvita mešanica je dosegla tlačno trdnost 138,5 MPa in upogibno trdnost 12,5 MPa, kar kljub delni nadomestitvi cementa z metakaolinom potrjuje zelo visoko mehansko zmogljivost UHPC. Za pridobitev dodatnih multifunkcionalnih lastnosti, kot sta izrazita vodoodbojnost in luminiscenčno emitiranje svetlobe, je bila uporabljena dvoslojna biomimetična površinska obdelava na osnovi nanodelcev SiO2 in luminiscenčnega prahu. Preizkusi omočenja so pokazali stabilno superhidrofobnost s kontaktnimi koti do 154,9°, luminiscenčni sloj pa je omogočil oddajanje vidne zelene svetlobe pri približno 520 nm. Rezultati potrjujejo, da sinergija optimizirane UHPC-matrice, bazaltnih vlaken in funkcionalnih površinskih slojev pomembno razširja uporabnost betona, zlasti pri trajnostno zasnovanih elementih, kjer sta nadzor razpok in zaščita pred vodo ključnega pomena, hkrati pa je zagotovljena pasivna nočna vidljivost brez zunanjega vira energije</dc:description><edm:type>TEXT</edm:type><dc:type xml:lang="sl">znanstveno časopisje</dc:type><dc:type xml:lang="en">journals</dc:type><dc:type rdf:resource="http://www.wikidata.org/entity/Q361785" /></edm:ProvidedCHO><ore:Aggregation rdf:about="http://www.dlib.si/?URN=URN:NBN:SI:DOC-HCGFKZ9Z"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:DOC-HCGFKZ9Z" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:DOC-HCGFKZ9Z/5dc6a7b9-1004-4439-83de-98acbac719f7/PDF" /><edm:rights rdf:resource="http://creativecommons.org/licenses/by-sa/4.0/" /><edm:provider>Slovenian National E-content Aggregator</edm:provider><edm:intermediateProvider xml:lang="en">National and University Library of Slovenia</edm:intermediateProvider><edm:dataProvider xml:lang="sl">Zveza društev gradbenih inženirjev in tehnikov Slovenije</edm:dataProvider><edm:object rdf:resource="http://www.dlib.si/streamdb/URN:NBN:SI:DOC-HCGFKZ9Z/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:DOC-HCGFKZ9Z" /></ore:Aggregation></rdf:RDF>
