概要 |
In this study, we examined carbonation of fly ash concrete which promoted pozzolanic reaction by increasing curing temperature before an accelerated carbonation test, and compared our results to long-...term carbonation test results. As a result, it was found that the carbonation rate of concrete exposed under natural conditions for 10 years was closer to that of specimens cured in water or an incubator at 40℃ than to that of specimens cured in water at 20℃ which is the curing temperature specified in JIS A 1153. Consequently, the accelerated carbonation test method by the high temperature curing will be valuable for evaluating the carbonation of fly ash concrete exposed under natural conditions.続きを見る
