| Abstract: | The destruction of the surface layer of concrete by a powerful microwave-radiation pulse is studied. The conditions for the
occurrence of shear and spall fractures in concrete at a given depth are found. The range of electrodynamic parameters within
which microwave radiation is the most effective for disintegration of concrete is found. The requirements for a microwave
generator that permit one to study experimentally the force action of electromagnetic radiation on concrete are formulated.
