Abstract

Based on accelerated carbonation tests, ID and 2D carbonation depths of fly ash concrete were measured. With the help of the influence coefficient Ks of steel bar existence and interaction coefficient K_c of 2D carbonation, the carbonation principle of concrete specimen with steel bar and 2D carbonation principle was analysed. The research results indicate that there are obvious interaction in corner of concrete specimen. The steel bar existence can inhibit concrete carbonation to a certain extent, the influence coefficient of steel bar existence and carbonation age conforms to logarithm relation.
