Since the mid-1980s, approximately 4,160,000 apartments have been built in Korea, and more than 70% of these apartments were high rise apartments having 11 floors or more. Meanwhile, most of the apartments were built in the wall-slab structure, and this kind of wall-slab high rise apartment is a building structure native to Korea of which its demolition cases cannot be found in other countries. Consequently, it can be said that it is absolutely necessary to develop and establish a safe and effective demolition technology in order to prepare for the upcoming time for demolition of wall-slab high rise apartments.
  So, in this paper, foundamental experiments were carried out using real wall-slabs of apartments. As one of experiments, high pressured brick walls were used for experiments, and relation between thickness of the wall and amount of adequate charge was obtained. Another wall was the shear wall of reinforced concrete, good relation between the shear wall and amount of adequate charge was obtained.
