45a - 70 - but also above all the binder used to consider. If, for example, the case of good stones, but less binding agent. before, the carefully executed fine blasting should afterwards give the impression that it is the recovery of large piles of nearly cleaned old stones. If some stones fly too far away, one of the charges will have been too strong. Such cases are to be considered retrospectively, especially since test blasts on heavily damaged and therefore to be laid down are not appropriate. Because of this, the experiences regarding wall resistance are also to be collected beforehand on the mentioned small objects. They must then be supplemented by a review of larger works and criticism afterwards. In general, one should not blow up at the level of the earth's equals even when laying houses; for even at masonry a large part of the ground floor is destroyed by the breaking down of the upper floors anyway, and the approximately standing ground floor wall can be easily removed later. This avoids unnecessary and harmful vibrations of the neighboring houses by the provocation of earth waves, which were particularly large, one wanted to go about the whole house from the basement to the body. If parts are to be blown out of an administrative building badly damaged by bomb hits or very large other buildings, in order to quickly remove the debris for the immediately re-establishing new construction, all associations, which transfer after the healthy parts, must be carefully separated beforehand. The walls can easily be blown off in places weakened by windows and doors. Carriers and running beams must be cut off beforehand and must be supported at the separation points in such a way as to prevent them from being able to clamp themselves again at the simultaneous ignition of all blasting points at the fall of the building part. It is then even in the hand to achieve the formation of sliding surfaces in such a way that the detached building part is stored as a pile of debris outside the old building outline line in front of the house.
