Determination of Concrete Composition and Testing its Properties in Fresh and Hardened State : Undergraduate Thesis

Beton pokriva oko 70% građenja, a koristi se u sve složenijim i najrazličitijim konstrukcijama. Cilj ovog rada bio je izraditi beton za armirano-betonsku podnu ploču parkirališta u morskoj luci. Ispitana su svojstva betona u svježem stanju metodom slijeganja, metodom rasprostiranja i Vebe metodom, te sadržaja zraka pomoću porometra. U očvrslom stanju kod starosti betona od 28 dana ispitana je tlačna čvrstoća, tvrdoća betonske površine te dinamički modul elastičnosti. Svi rezultati ispitivanja prikazani su u radu.Concrete covers about 70% of construction, and is used in increasingly complex and various structures. The aim of this study was to make concrete for reinforced concrete floor slab parking in a seaport. We studied the properties of concrete in fresh state using slump method, flow method and Vebe method, as well as content of the air using porometer. When hardened, at the age of concrete of 28 days, the compressive strength is tested, the hardness of the concrete surface, and the dynamic modulus of elasticity. All results of testing are presented in the work
