- This study aims to predict demolition waste generation rate (DWGR) of the detached house by their types and materials when they are demolished. To achieve this objective, required data was collected based on material information of the buildings investigated before demolition. By using the established database in this research, CART analysis was conducted, with the buildings’ types and materials as analysis factors, to identify what affects the generation of waste concrete and to estimate index of waste generation. The results were as follows. First, the most influential factor on the generation of waste concrete was types of buildings. Second, generation of waste concrete of RC-type and wood-type buildings was not affected by materials, while that of masonry-type buildings was affected by roof materials. Masonry-type buildings were divided into two categories by roof materials: i) buildings with slab and slab with roof tiles as roof materials and ii) buildings with roof tiles and slate as roof materials. Third, amounts of waste concrete of RC-type and wood-type buildings were 0.324m3/m2 and 0.018 m3/m2, respectively, and those of masonry-type buildings with roof materials of slab and slab with roof tiles and the other masonry-type buildings were 0.127 m3/m2 and 0.040 m3/m2, respectively.
