Particular attention is given to fiber-reinforced concrete, where different types of fibers are employed to enhance mechanical performance, durability, and long-term behavior in standard, high-strength, and recycled-aggregate concretes. Research objectives \u2022 Use of various fiber types, including recycled steel fibers, industrially produced steel fibers, and hybrid fiber systems. \u2022 Improvement of concrete mechanical properties, especially strength, resistance to crack initiation and propagation, and reduction of shrinkage. \u2022 Assessment of concrete durability, including water absorption, carbonation, and long-term structural performance. \u2022 Application of fiber-reinforced concrete in mixes with recycled aggregates to reduce the consumption of primary raw materials. \u2022 Design of more efficient and slender concrete structures, such as pavements, while maintaining the required service life.<\/p>\n<p>\u00a0<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone  wp-image-7354\" src=\"https:\/\/ustarch.sav.sk\/sk\/wp-content\/uploads\/sites\/2\/sustain3-242x300.jpg\" alt=\"\" width=\"359\" height=\"445\" srcset=\"https:\/\/ustarch.sav.sk\/sk\/wp-content\/uploads\/sites\/2\/sustain3-242x300.jpg 242w, https:\/\/ustarch.sav.sk\/sk\/wp-content\/uploads\/sites\/2\/sustain3.jpg 518w\" sizes=\"auto, (max-width: 359px) 100vw, 359px\" \/> <img loading=\"lazy\" decoding=\"async\" class=\"alignnone  wp-image-7353\" src=\"https:\/\/ustarch.sav.sk\/sk\/wp-content\/uploads\/sites\/2\/sustain2-240x300.jpg\" alt=\"\" width=\"354\" height=\"443\" srcset=\"https:\/\/ustarch.sav.sk\/sk\/wp-content\/uploads\/sites\/2\/sustain2-240x300.jpg 240w, https:\/\/ustarch.sav.sk\/sk\/wp-content\/uploads\/sites\/2\/sustain2.jpg 522w\" sizes=\"auto, (max-width: 354px) 100vw, 354px\" \/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Research in sustainable construction materials focuses on the development of various concrete types with a reduced environmental impact through the use of recycled and secondary&#8230;<\/p>\n","protected":false},"author":4,"featured_media":0,"parent":5003,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":"","_links_to":"","_links_to_target":""},"class_list":["post-7309","page","type-page","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/ustarch.sav.sk\/sk\/wp-json\/wp\/v2\/pages\/7309","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ustarch.sav.sk\/sk\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/ustarch.sav.sk\/sk\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/ustarch.sav.sk\/sk\/wp-json\/wp\/v2\/users\/4"}],"replies":[{"embeddable":true,"href":"https:\/\/ustarch.sav.sk\/sk\/wp-json\/wp\/v2\/comments?post=7309"}],"version-history":[{"count":2,"href":"https:\/\/ustarch.sav.sk\/sk\/wp-json\/wp\/v2\/pages\/7309\/revisions"}],"predecessor-version":[{"id":7535,"href":"https:\/\/ustarch.sav.sk\/sk\/wp-json\/wp\/v2\/pages\/7309\/revisions\/7535"}],"up":[{"embeddable":true,"href":"https:\/\/ustarch.sav.sk\/sk\/wp-json\/wp\/v2\/pages\/5003"}],"wp:attachment":[{"href":"https:\/\/ustarch.sav.sk\/sk\/wp-json\/wp\/v2\/media?parent=7309"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
