The investigation is aimed particularly to the microstructure of concrete after application of the silicate protection layer and its porosity. An attention will also be paid to the anaiysis of water and salt transport processes. Orientat\u00EDon values of moisture diffusivity will be determined by an approximate method based on sorptivity measurement, the dependence of moisture diffusivity on moisture will determined by measuring the moisture profiies using the capacitance method and a subsequent solution of inverse probl\u00E9m of moisture conduction. Water vapor permeability will be measured by the standard cup method. The permeability measurement will also be complemented by using the Figg test. Sorption isotherms and water retention curves will be determined as well. The salt diffusion coefficient will be"@en . "http://www.isvav.cz/projectDetail.do?rowId=GA103/05/2376"^^ . "21"^^ .
