Sekundarni naslov:	Technological and organizational aspects of steel fiber reinforced concrete construction
Sekundarni povzetek:	The present work is divided in an introduction, five substantive chapters and conclusions. The first substantive chapter represents development of the usage of separate sorts of fibers, suitable to reinforce the concrete structure. The rest of the chapter concentrates on the detailed presentation of steel fiber reinforced concrete. So in the second substantive chapter steel fibers that are used for reinforcing the concrete structure are defined, together with the production procedures, their physical and mechanical properties and aspects of usages. The work also deals with the influence of steel fibers added to concrete regarding the ready- mixed concrete as well as some more important mechanical features of solid concrete. The following chapter presents the technological procedures of steel fiber reinforced concrete constructing including design, mixing procedures, implanting, processing, care and protection. The chapter is substantively subdivided according to different types of concrete which more often integrate steel fibers such as vibrated, shotcrete, self- compacting and slurry- infiltrated types of concrete. Substantive chapter four concentrates on fiber reinforced concrete and its most common usage in Slovenia. The last substantive chapter brings a comparative study of three different versions of industrial floors based on steel fiber reinforced concrete and version based on classical reinforced concrete. The cost, practical completion as well as the quality were being compared in the study. Its results showed general justification of fiber reinforced concrete usage on the assumption of professional work performance. Conclusions are presented at the end.

Povzetek (ePrints):	Diplomsko delo je razdeljeno na uvod, pet vsebinskih poglavij in zaključke. V prvem vsebinskem poglavju je predstavljen razvoj uporabe posameznih vrst vlaken, primernih za ojačitev betonske strukture. V nadaljevanju smo se omejili na podrobnejšo predstavitev mikroarmiranih betonov z jeklenimi vlakni. Tako so v drugem vsebinskem poglavju opredeljena jeklena vlakna, ki se uporabljajo za ojačitev betona, in opisani postopki njihove proizvodnje, njihove fizikalne in mehanske lastnosti ter vidiki uporabe. Obravnavani so vplivi betonu dodanih jeklenih vlaken na obdelovalnost sveţe betonske mešanice in na pomembnejše mehanske lastnosti strjenega betona. V naslednjem vsebinskem poglavju so opisani tehnološki postopki gradnje z mikroarmiranimi betoni z jeklenimi vlakni, ki obsegajo projektiranje mikroarmiranih betonskih mešanic, postopke mešanja, vgrajevanje, zaključno obdelavo in nego ter zaščito površin. To poglavje je vsebinsko razdeljeno glede na vrste betonov, pri katerih se najpogosteje kot dodatek uporabljajo jeklena vlakna, in sicer so to vibrirani, brizgani, samozgoščevalni in prepaktirani betoni. V četrtem vsebinskem poglavju so predstavljena najpogostejša področja uporabe mikroarmiranih betonov z jeklenimi vlakni v Sloveniji. V zadnjem vsebinskem poglavju je predstavljena primerjalna analiza treh variant izvedbe industrijskega tlaka iz mikroarmiranega betona, ki se razlikujejo v razdaljah med stiki, in varianto izvedbe klasično armiranega betonskega industrijskega tlaka. Primerjali smo stroške, izvedbo in kakovost obravnavanih industrijskih tlakov. Rezultati analize so pokazali vsesplošno upravičenost gradnje z mikroarmiranim betonom z jeklenimi vlakni ob predpostavki, da je rokovanje z njimi pravilno izvedeno. Na koncu dela so zbrani zaključki.
