Аннотация: This research evaluates the effect of single-component sodium chloride solution in comparison with multicomponent commercial sleet-proof reagents (SPR) on the cement stone of side stone concretes of different compositions. Furthermore, it estimates manufacturing technologies: vibration casting - composition №1 - with a water-cement ratio of 0.4 and a strength of up to 70 MPa and №2 – W/C ˃0.4, strength <40 MPa. The composition №3 is manufactured using class B30 vibropress technology. Samples of each composition are saturated with salt solutions – single-component 10% NaCl or multicomponent commercial SPR of 10 or 30% concentration. Multicomponent SPR containing sodium and calcium chlorides has a greater impact on concrete in comparison with single-component salt. However, a higher concentration of the SPR solution may have a less destructive effect on the concrete. The lowest accumulation of chlorides is observed in vibropressed concrete, despite the high value of water absorption of samples. The permeability of concrete made using vibropress technology is higher than that of vibration casting ones, but destructive processes develop much more slowly. Thus, the nature of the pore space, rather than the volume, has a greater influence on their flow. © 2021, The Author(s), under exclusive license to Springer Nature Switzerland AG.
