Sekundarni naslov:	Assessment of stability of fresh mortars with electronical conditivity method
Sekundarni povzetek:	Diploma work deals with the possibility of estimating stability of fresh mortars in mould with non-destructive electrical conductivity method. Specially designed measuring system with considerable number of brass electrodes was used to monitor time changes in electrical conductivity of mortar between each pair of electrodes inserted in mould at four different heights. The method was evaluated with the help of different mortar mixtures, also with different water-to-cement ratios. Finally, measurements of electrical conductivity were carried out on deliberately segregated mortar with high fluidity. Obtained results were compared with the results of measurements of fresh mortar settings and visual estimation of homogeneity of hardened mortars on cut surfaces along the mould height.

Povzetek (ePrints):	V diplomski nalogi smo preverjali možnost ocene stabilnosti svežih malt v kalupu s pomočjo neporušne metode merjenja električne prevodnosti. S posebej zasnovanim merilnim sistemom z večjim številom parov medeninastih elektrod smo spremljali časovno spreminjanje električne prevodnosti med paroma elektrod vgrajenima v malto na štirih različnih višinah kalupa. Metodo smo najprej validirali s pomočjo različnih maltnih mešanic, tudi z maltami z različnim vodo-cementnim razmerjem. Na koncu smo opravili meritev na namerno segregirani malti z visoko sposobnostjo tečenja. Dobljene rezultate smo primerjali z rezultati vezanja svežih malt in vizualne ocene homogenosti strjenih malt na rezani površini malt vzdolž višine kalupa.
