| Abstract |
In this study, the carbonation depth according to the type of surface treatment materials was evaluated by applying the surface treatment
method to the fire damaged fiber-reinforced high-strength concrete. As a result of the study, it was confirmed that the carbonation resistance
according to the type of surface treatment materials was superior in the order of a polymer coating, lithium silicate impregnation, and sodium
silicate impregnation. In addition, in the case of polymer coating, it was confirmed that the carbonation did not proceed significantly due to
accelerated carbonation even if scratches of 0.5mm or less, which may occur during the use of building after construction. |
