Sekundarni naslov: The Influence of Steel Fibres Content and Pre-Soaked Lightweight Aggregate on Shrinkage of High Strength Concrete
Sekundarni povzetek: This thesis studies high strength concrete reinforced with steel fibers and pre-soaked lightweight aggregate. Steel fibers added to the steel mixture represented 0.5% of the total volume. 12% of the aggregate was replaced with pre-soaked lightweight aggregate. The focus of the analysis was on the autogenous shrinkage, which is very distinct at high strength concrete. The shrinkage was measured electronically during the first day. Later we measured it with a mobile displacement transducer.Beside the autogenous shrinkage the drying and the total shrinkage of concrete were also analysed. Using experiments the compressive strengths of the concrete were measured. It can be concluded that by adding steel fibers and pre soaked aggregate shrinkage is little affected, but the compressive strength of concrete improves.

Povzetek (ePrints): V diplomski nalogi obravnavam betone visokih trdnosti, ki so vsebovali jeklena vlakna in predhodno namočen lahek agregat. V betonski mešanici je bilo 0,5% prostornine jeklenih vlaken. 12% agregata smo zamenjali s predhodno namočenim lahkim agregatom. Poudarek študije je na analizi avtogenega krčenja, ki je pri betonih visokih trdnosti izrazitejše v primerjavi z betoni običajnih trdnosti. Avtogeno krčenje smo v prvem dnevu merili elektronsko, saj je takrat dogajanje najbolj burno, v naslednjih dneh pa smo merili s pomočjo nasadnega deformetra. Poleg avtogenega krčenja smo analizirali še krčenje zaradi sušenja in celotno krčenje vzorcev. Eksperimentalno smo določili tlačne trdnosti izdelanih betonov. V svoji diplomski nalogi navajam ugotovitev preiskav, da dodatek jeklenih vlaken in predhodno namočenega lahkega agregata na krčenje betona bistveno ne vpliva, precej pa se izboljša tlačna trdnost betonov.
