METHOD OF ELECTRICALLY DESTROYING CONCRETE AND/OR MORTAR AND DEVICE THEREFOR

摘要

This invention relates to a method of electrically destroying a ferroconcrete body which comprises steps of conducting an alternating magnetic flux generated at an exciting coil to a ferromagnetic material present in the inner part of a ferroconcrete body or conducting an alternating magnetic flux generated at an exciting coil connecting capacitors in parallel to a part or entire part of a coil to said ferromagnetic material thereby to constitute a controlled magnetic induction circuit mainly including said ferromagnetic material and magnetic inductor, and raising the temperature of said ferromagnetic material, and a device therefor.
