Then we need - as I said in the theoretical model - the heat diffusion in concrete, we have diffusion of bound water and diffusion of water vapour. You see the expressions of the diffusivity, here for bound water, here for water vapour.
Here you see the diagrams for different temperatures. What is important to show, is that the behaviour is completely different between the tools, so you cannot just sum the two up. They have a completely different behaviour.
