Abstract

V diplomski nalogi smo predstavili izdelavo Delta Bloc varnostnih ograj, ki jih izdeluje SGP Pomgrad ABI, d. o. o. Betonske varnostne ograje so izdelane iz samozgoščevalnega betona. Prednost samozgoščevalnega betona je v bolj homogeni strukturi strjenega betona in s tem v izboljšanih lastnostih armirano betonskih elementov. Omogoča večjo hitrost vgrajevanja, hitrejše napredovanje del, izboljšano delovno okolje in manjše število delavcev pri vgraditvi betona. Prav zato so pri SGP Pomgrad ABI, d. o. o., samozgoščevalni beton uporabili za izdelavo Delta Bloc varnostnih ograj. V diplomski nalogi je opisanih več različnih preizkusov na samozgoščevalnih betonih, podrobneje pa je opisana preiskava zunanje odpornosti betonske površine na zmrzovanje-tajanje. Preizkus zunanje mrazoobstojnosti je preizkus, ki upošteva navodila, opisana v SIST 1026:2008. Ta preizkus nam podaja odpornost površine betona proti zmrzovanju-tajanju ter se ocenjuje s količino materiala, ki se odlušči s preiskovalne površine po n ciklusih izmeničnega zmrzovanja ter tajanja. Preizkus smo opravili na samozgoščevalnem betonu ter na klasičnem betonu. Na koncu je podana primerjava rezultatov med obema betonoma.

Secondary title:	Use of self compacting concrete at production Delta Bloc safety fences
Secondary abstract:	The thesis is about the production of Delta Bloc safety fences by SGP Pomgrad ABI d.o.o. The safety fences are made of self-compacting concrete. There are advantages of using self-compacting concrete. It can be placed at a faster rate, it saves labour and there are shorter construction periods. It improves consolidation around reinforcement and bond with reinforcement. For all the benefits of self-compacting concrete SGP Pomgrad ABI d.o.o. uses it in the production of Delta Bloc safety fences. In my thesis several test procedures of self-compacting concrete have been presented. In order to predict the frost-resistance of self-compacting concrete, certain laboratory tests have to be performed. The frost resistance test follows the instructions set in SIST 1026:2008. The test is about how the surface of the concrete reacts to frost action. It has been carried out on self-compacting and classical concrete. Findings are based on comparison of the two tests.
