Sažetak
This paper presents the results of an experimental study of the freeze-thaw resistance with de-icing salts (resistance to scaling) of three slag-based alkali-activated (AA) concrete mixes and the reference OPC concrete mix. The scaling resistance was tested on the samples subjected to the 7, 14, 28, 42 and 56 freezing and thawing cycles with 3% NaCl solution as freezing medium. The results showed that the increased sodium silicate content enhances the scaling resistance of the AA concrete. OPC concrete exhibited much higher scaling resistance up to 42 cycles, after which it showed severe damage, while the scaling of AA concrete mixes became more moderate after 7 cycles of testing.
