要旨 The aim of the research is to understand how carbon dioxide and chloride penetrate into post-fire concrete which can be used without repairing, by investigating the moisture transfer in concrete. Concrete specimens with water-to-cement ratios of 0.35 and 0.45 were heated up to 350 °C. Then, the moisture transfer, and accelerated carbonation and chloride penetration depths in the specimens were measured. As a result, the carbonation and chloride penetration depths of the heated specimen were larger than the unheated specimen because of low moisture content and micro-cracks.
