Abstract
Betoni visokih uporabnih svojstava su vrsta betona kojim se postižu poboljšana svojstva konstrukcija u upotrebi u odnosu na normalni beton. Pažljivim projektiranjem sastava betona i upotrebom kvalitetnog materijala moguće je zadovoljiti visoke kriterije opterećenja i trajnosti. Tlačna čvrstoća betona je osnovno svojstvo odabira i klasifikacije, ali često su svojstva kao modul elastičnosti ili propusnost kritični faktori. Kako bi se postigli traženi zahtjevi smanjuje se količina vode te se povećava količina veziva i kemijskih dodataka. Takvim projektiranjem postižemo tražene zahtjeve, ali u pogledu čvrstoće mješavine postaju predimenzionirane te ekonomski i ekološki neisplative. U ovom radu provedeno je laboratorijsko istraživanje na uzorcima morta te je prikazan utjecaj pojedine kombinacije veziva na svojstva trajnosti betona visokih uporabnih svojstava. Ispitivanja su specificirana na ponašanje konstrukcija u maritimnom okolišu, odnosno konstrukcije izložene kloridima iz morske vode. Korištena veziva su silicijska prašina, leteći pepeo, vapnenac i kvarc. U svježem stanju su provedena ispitivanja konzistencije, temperature, gustoće i sadržaja pora. Uzorci su njegovani u vlažnoj komori do ispitivanja svojstava u očvrsnulom stanju. Provedena ispitivanju su čvrstoća na savijanje, tlačna čvrstoća, koeficijent difuzije i električna otpornost.
Abstract (english)
High- performance concrete is a type of concrete with improved properties in relation to the normal concrete. Taking care of the design mix and using high quality materials it is possible to meet high criteria of construction load and durability. Main feature of selecting and classification is the compressive strength but often the critical factors are properties like modulus of elasticity or permeability. In order to achieve designed requirement, the amount of water is reduced, and the amount of binder and chemical additives are increased. With such design we achieve the requirements but in terms of strength mixtures are oversized and economically and ecologically unprofitable. This paper presents a laboratory study performed on mortar samples showing the impact of certain combination of binders on durability properties of the high-performance concrete. The tests are specified on the behaviour of structures in maritime environment that is structures exposed to chlorides from sea water. Used binders are silica fume, fly ash, limestone, and quartz. In the fresh state consistency, temperature, density, and pore content were performed. Samples were cured in humid chamber until testing. The conducted tests were flexural strength, compressive strength, chloride diffusion coefficient and electrical resistivity.
