Summary:Title screen
Based on orthogonal design, 10 indoor experiments of high voltage pulse discharge breaking concrete and measurement of crack depth loss of concrete on three factors such as applied voltage, pulse number and discharge electrodes gap were carried out at three levels. The effects of these three factors on the crack depth loss of concrete were studied by using range analysis and significance analysis test data. When the applied voltage is about 320 kV and the pulse number is 5, the crack depth loss of concrete can be broken by high voltage pulse discharge that is the largest. Our study concerns the energy transferred from the plasma created in the channel of a discharge to a concrete substance. Our study includes both experiment and modeling. The possibility of generating nanoparticles of Si, Al, Fe, Ca. A thermodynamic study of the plasma-chemical processes occurring in the channel of the discharge was carried out, which made it possible to determine the possibility of the formation of certain amounts of chemical compounds under given conditions. Thermodynamic analysis uses the universal TERRA program.
