要旨 The effects of cooling method and elapsed time after heated on the carbonation resistance of the concrete subjected to high temperature were investigated by an accelerated carbonation test. The results indicate that the carbonation depth of the concrete increased with temperature for any cooling methods, and was smaller when the concrete was cooled in the air than by water. The longer the elapsed time after subjected to fire, the lower the carbonation resistance. The application of the performance-modifying agent to the heated concrete could improve the carbonation resistance of the concrete.
