Process of concrete carbonation under aggressive carbon dioxide attack

摘要

It is proved, that in a wide range of concrete saturation (which means degree of pores filling with water) the principal factors controlling corrosion (carbonation) of concrete are the processes proceeding in a gaseous and liquid phases; the formulas recommended for engineering calculations are presented. For the approximate analysis the humidity, temperature and concentration of an aggressive component could be considered as constant. The basic purpose of the given research is the calculation of speeds of movement and depth of front of corrosion (carbonation), that enables to predict service life of the structure.
