Sekundarni naslov:	Impact of internal water reservoirs in high-strength concrete on drying shrinkage
Sekundarni povzetek:	This thesis discussed the impact of internal curing on shrinkage of high-strength concretes, especially due to drying shrinkage. The shrinkage is more pronounced in the concrete due to the lack of water during the process of hydration, which is the result of low water/cement ratio. Among the several methods of internal curing of concretes internal curing with presoaked lightweight aggregate was selected. The impact of internal curing with pre-soaked lightweight aggregate concrete was studied in two different fractions of lightweight aggregate, 0-2 mm and 2-4 mm. Shrinkage was measured 28 days. Based on the analysis of the results it can be concluded that shrinkage due to the drying in concrete, which was cured with light aggregates, was smaller compared to concrete, which was not internally cured.

Povzetek (ePrints):	V diplomski nalogi obravnavamo vpliv notranje nege na krčenje betonov visoke trdnosti, predvsem na krčenje zaradi sušenja. Krčenje je pri teh betonih izrazitejše zaradi pomanjkanja vode med procesom hidratacije, ki je posledica nizkega vodovezivnega razmerja. Med več načini notranje nege betonov smo izbrali notranjo nego s predhodno namočenim lahkim agregatom. Vpliv notranje nege s predhodno namočenim lahkim agregatom smo raziskovali na betonih z dvema različnima frakcijama lahkega agregata, 0-2 mm in 2-4 mm. Krčenje smo merili 28 dni. Na podlagi analize rezultatov lahko sklepamo, da je krčenje zaradi sušenja pri betonu, ki smo ga negovali z lahkim agregatom, manjše v primerjavi z betonom, ki ni bil notranje negovan.
