Secondary title: Resistance of highly flowable concrete made from crushed limestone aggregate
Secondary abstract: The diploma thesis deals with the resistance of concrete made by crushed limestone aggregate, tap water and cement CEM II/A-M (LL-S) 42,5R (concrete L2) against penetration of water under pressure. Beside this, fresh concrete properties were determined and compressive and splitting tensile tests were carried on hardened concrete. We studied influence of low and increased temperatures during setting and hardening of the concrete on the hardened concrete properties under consideration. Influence of reinforcing bars with larger and smaller diameter used for reinforcement of flexural element with selected reinforcement rate was also studied, through penetration of water under pressure into cracked concrete. Further on, study of influence of honeycombs, bug holes and cold joints on the resistance of the concrete against penetration of water under pressure was carried out. At the end comparison between properties of concrete L2 and the same properties of concrete made by gravel from river Sava and cement CEM I 42,5R was carried out.

Abstract (ePrints): V diplomski nalogi smo najprej ugotavljali odpornost betona izdelanega iz drobljenega apnenčevega agregata in cementa CEM II/A-M (LL-S) 42,5R (beton L2) na njegovo odpornost proti prodoru vode pod pritiskom. Poleg tega smo preskušali tudi njegove lastnosti v svežem stanju ter njegovo tlačno in cepilno natezno trdnost v strjenem stanju. Zanimal nas je vpliv nizkih in povišanih temperatur v času vezanja in strjevanja betona na obravnavane lastnosti. Poleg tega pa smo študirali tudi vpliv razpok, ki so se oblikovale pri enaki obtežbi upogibnega elementa z izbranim deležem armature, armiranega z armaturnimi palicami različnih prerezov, ter vpliv gnezd, zračnih žepov in hladnih stikov v strukturi betona na njegovo odpornost proti prodoru vode. Na koncu smo naredili primerjavo med obravnavanimi lastnostmi betona L2 in betona izdelanega iz savskega proda in cementa CEM I 42,5R.
