Abstract


The paper reviews the phenomenon of damage of the concrete surface - scaling - due to cyclic freezing and thawing in the presence of de-icing salts. A possibility to replace air-entraining admixtures by other techniques is considered. The main kinds of air pores in the concrete and the process of water filling and freezing of water inside the pore structure are described. A review of publications concerning the mechanism of both internal and external deteriorations of concrete structure due to cyclic freezing and thawing is presented. The next part is devoted to characterisation of concrete with regard to scaling phenomenon.
