Abstract The use of high power microwaves to perform explosive spalling of surface concrete is a promising technique with applications in the area of concrete
facilities decommissioning. The mechanism that creates explosive spalling is an interactive process of the thermal stress from high temperature
gradients and the pore pressure generated from the water vaporization. In order to better predict the total stress distribution, the temperature has to be
calculated by including the effect of water vaporization and water transport through a porous medium. In this paper, a one dimensional model solving
the heat and diffusion equation for liquid and vapor phase… More >
