| Outline of Final Research Achievements |
In this study, the large size specimens for each of the vacuum dewatered concrete and the concrete using permeable form were manufactured. And the density test, the compressive strength test, the estimation of mix proportion and the accelerated carbonation test were carried out using the φ 50mm core specimens obtained from each the large size specimen. As a result, the density distribution, the compressive strength distribution, the estimated water cement ratio and the carbonation properties for each of the vacuum dewatered concrete and the concrete using permeable form were clarified. Also the possibility of constructing the carbonation prediction model of concrete by dewatering methods was shown by clarifying that the estimated water cement ratio has a high correlation with the carbonation rate ratio.
