In this study, Based on the constructed model in advance, we suggested the macro prediction method of shrinkage cracking reduction in concrete using expansive additives, and the method was verified. In addition, extended application of model to building, the strain of walls and slabs on building was estimated by model and the generated stress was estimated thereby comparing this with the result by existing method to verify the model's applicability and the validation of our model. From examination of theoretical model for concrete using expansive additives to examination for building levels, furthermore 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.
