|Abstract: ||Abstract: An experimental investigation was carried out to study the effect
of carbonation on mechanical properties and durability of concrete.
Ordinary portland concretes (OPC) with water/cement ratios of 0.58
and 0.48 and self-compacting concretes (SCC) with water/binder
ratios of 0.40 and 0.36 were used in this study. Compressive strength
test, splitting strength test, electrical resistivity test, rapid chloride
penetration test (RCPT), open circuit potential method and alternative
current (AC) impedance method were performed to estimate the
properties of concrete. Test results showed that carbonation may
compensate some concrete properties such as compressive strength,
splitting strength, electrical resistivity and chloride ion penetration.
However, corrosion test results showed that carbonation increases
corrosion rate of reinforcing steel.
