THE EFFECT OF DIFFERENT DEGRADATION ENVIRONMENTS ON CHLORIDE CONTENT AND CARBONATION IN CONCRETE
Abstract
Different forms and combinations of degradation attacks cause the damage of concrete and reinforced concrete structures. Among the most usual belong ingress of chlorides and carbonation that influence the quality of the concrete and also affect its ability to protect reinforcement. The resistance of concrete against the mentioned attacks is given also by other surrounding conditions, like temperature, mechanical load, etc. In this paper, experimental findings are presented focused on the investigation of the effect of three different degradation environments, namely freeze-thaw cycles, immersion in salt solution and placing in carbonation chamber, on concentration of chlorides and degree of carbonation in concrete profile. The degradation environments were varied in order to compare the effect of each environment separately and also the effect of combined environmental action.
