| Outline of Final Research Achievements |
In this study, the mechanical properties, volume changes and creep of concrete mixed with expansive additives, which is used as a countermeasure for cracking and shrinkage, were modeled and the model was verified. The results of an experimental verification of the model showed that the values predicted by the model correlated closely with the experimental values. In addition, the generated stress was estimated using the modeled creep phenomenon to calculate changes in the stress under the restraint condition, thus allowing a comparison with experiment to verify the applicability of model and the validation of the stress prediction technique. And suggests the macro prediction method for shrinkage reduction and cracking control effects was can be supply practical data in application of expansive concrete and utility in the future.
