Abstract: Abstract: In this study, the behavior of reinforced concrete under
carbonation and in a salt environment was investigated. Three
types of cements- Type I cement, Type II cement and highalumina
cement (HAC) - were used to study the influence of
cement on reinforced concrete behavior. To simulate chloridecontaminated
concrete, 1% NaCl (by cement weight) was added
to some groups of specimens. Results revealed that the carbonation
released chloride ions from Friedel's salt, which increased
the chloride content near the carbonation front. The carbonation
rate of HAC concrete was higher than that of Type I
and Type II cement concrete. The corrosion rate of rebars
embedded in HAC concrete was slower than that of rebars
in Type I and Type II cement concrete because of the denser microstructure
of HAC. However, carbonation enhanced the corrosion
rate of rebars embedded in HAC concrete because of
the release of chloride ions from Friedel's salt.
