| Abstract: | In an old concrete building made available by the Stockholm Real Estate Office, several experiments at full‐scale were made on different methods of localised cutting, including controlled blasting with charges inserted into drilled holes and with lay‐on, metal‐enclosed explosives. Some punching shear to the rear of the wall was noted with the latter, which sometimes produced violent shock waves. The inserted charges performed well, however, and were found to be more economical and environmentally better than conventional cutting methods. The author works at the Swedish National Testing Institute. |
