Surface Layer Parameter of Concrete in Relation to Deicing Salt Scaling Resistance

Article Preview

Abstract:

The porous structure together with surface layer, made by the compaction of concrete mix designed and by the following treatment of concrete placed, has a decisive influence on the penetration of aggressive media into the inside of concrete structure. In principle, it influences the parameters of hardened concrete and the transport of liquid and gaseous media. The surface layer of concrete is contacted as the first with aggressive substances and is an entrance gate for unwanted ones.
