ABSTRACT / SAŽETAK:

S obzirom na to da je beton trenutno najrasprostranjeniji građevinski materijal, njegova čvrstoća i izdržljivost su njegove bitne karakteristike. Nedavna dostignuća u vidu primene  vlakna nanodimenyije, kao što su ugljenične nanotube i grafen oksid, poboljšala su performanse betona. Grafen oksid (GO) je dvodimenzionalni planarni list komprimovanih atoma ugljenika u konfiguraciji saća debljine 0,335 nm. GO je obećavajući nanomaterijal zbog svojih jedinstvenih svojstava, naime, dobio je međunarodnu pažnju zbog svojih izvanrednih mehaničkih, optičkih i termičkih svojstava. Pored regulacije sekundarnog mehanizma hidratacije, dodavanjem GO betonu poboljšavaju se njegove mehaničke performanse, izdržljivost, samozarastanje i druge multifunkcionalne karakteristike. Ova studija predstavlja ispitivanje svojstava betona sa dodatkom GO. Pripremljena su četiri različita projekta betonske mešavine. GO je dodat u količinama od 0,01, 0,02, 0,03 i 0,06 %. Hidratacija je analizirana diferencijalnom termičkom analizom. Praćene su mehaničke čvrstoće u trajanju od 28 dana i otpornost na mraz sa solima za odleđivanje tokom 56 ciklusa.
