Secondary title: Resistance of highly flowable concrete made from river Sava gravel from the Krško basin
Secondary abstract: The diploma thesis deals with the resistance of concrete made by Sava river gravel from the Krško basin, tap water and cement CEM I 42,5R (concrete P1) or cement CEM II/B-M(W-L) 42,5N (concrete P2) against penetration of water under pressure. Beside this, fresh concrete properties were determined and compressive and splitting tensile tests were carried on hardened concretes. For the concrete P1 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 P1. At the end, study of influence of honeycombs, bug holes, segregation and cold joints on the resistance of the concrete P1 against penetration of water under pressure was carried out.

Abstract (ePrints): V diplomski nalogi smo ugotavljali odpornost betona izdelanega iz savskega proda iz krške kotline in cementa CEM I 42,5R (beton P1) ali cementa CEM II/B-M(W-L) 42,5N (beton P2) na njegovo odpornost proti prodoru vode pod pritiskom. Poleg tega smo preskušali tudi lastnosti betonov v sveţem stanju ter njuno tlačno in cepilno natezno trdnost v strjenem stanju. Pri betonu P1 pa nas je zanimal tudi vpliv nizkih in povišanih temperatur v času vezanja in strjevanja betona na obravnavane lastnosti strjenega betona. Poleg tega pa smo za beton P1 študirali tudi vpliv razpok, ki so se oblikovale pri enaki obteţbi upogibnega elementa z izbranim deleţem armature, armiranega z armaturnimi palicami različnih prerezov, ter vpliv gnezd, zračnih ţepov, segregacije in hladnih stikov v strukturi betona na njegovo odpornost proti prodoru vode.
