"The corrosion salt effects in building materials are mainly related to their crystallisation from solutions, recrystallisation of solid state, sometimes with chemical reaction. The ions can be found rarely in building materials at usual conditions, but for instance due to capillary action of ground water the capillary forces may cause the rising of salts concentration and the degradation of building material. If the salts in porous system of building material are in the form of solution, there is no danger. But in the moment of water evaporation the salts form hydrates and their crystallisation pressure is higher than the binding forces of material particles and it leads to destruction of material matrix. Hence it is important to study the transportand storage conditions of salts in building materials. On the top of it there is no database of salt transport and storage parameters in building materials, which is necessary to the simulation of materials behaviour in the salt solutions.
