Abstract
Recently, the development of proper disposal process of construction wastes has been an important subject, and it is also required to the ALC panel. In this study, it is examined the emitted conditions of the ALC rubbles on construction sites. As a result, the ALC rubbles such the shapes as a block or powder come to occur by cutting or scraping the ALC panel, and the emitted volume of ALC rubbles was grasped in the feasible study on construction site. Finally considering the results of the survey and the feasible study, the material flow model of the ALC panel was clarified.
