Povzetek

Velike količine gradbenih odpadkov, ki nastajajo pri raznih sanacijah, rušitvah in obnovah objektov, predstavljajo velik problem za okolje. V diplomski nalogi smo preučili možnost uporabe recikliranega betona kot agregata za proizvodnjo konstrukcijskih betonov. Reciklirani agregat smo pridobili iz rušenja betonske stene iz betonskih zidakov. Ruševine smo zdrobili z drobilcem in jih nato presejali na sejalni napravi na ustrezne frakcije in sicer 4/8, 8/16 in 16/31.5 mm, frakcijo 0/4 mm smo nadomestili z naravnim agregatom. Dobljeni reciklirani agregat smo uporabili za betonske mešanice po enotni recepturi z različni deleži frakcij agregata. Dobljenim preizkušancem, kockam s stranico 150 mm, smo v laboratoriju določili tlačno trdnost. Na podlagi dobljenih rezultatov smo ugotovili, da naš beton ne dosega vrednosti za proizvodnjo zahtevnejših konstrukcijskih elementov, lahko bi ga pa uporabili za stabilizacije tal, drenažne betone in druge nezahtevne betonske konstrukcije.

Sekundarni naslov: RECYCLED CONCRETE AS AGGREGATE FOR STRUCTURAL CONCRETE PRODUCTION
Sekundarni povzetek: Large quantities of construction waste generated at various renovations and demolitions of buildings represent a major problem for the environment. In this thesis, we studied the possibility of using recycled concrete as an aggregate for the manufacture of structural concrete. Recycled aggregates were obtained from the demolition of the concrete walls from concrete blocks. Ruins were crushed by the grinder and then screened in screening machines at the appropriate fractions, namely 4/8, 08/16 and 16 / 31.5 mm, fraction 0/4mm has been replaced with natural aggregates. The resulting recycled aggregate was used for the concrete mix at a single recipe with different proportions of fractions of aggregates. Obtained test specimens, cubes with side measure 150 mm, were tested for compressive strength in the laboratory. Based on the results, we found that our concrete does not reach the level of production of complex structural elements, but could be used for soil stabilization, drainage concrete and other unpretentious concrete structures.
