Hollow Brick

[samiraaien]

Hi,
I modeled an old wall construction that I already measured the temperature and Relative humidity of each layer.I don't have enough information about brick properties of modeled wall i have just thermal conductivity (0.4w/mk) and thickness?(25cm). I guess the brick is hollow brick or hollow concrete block , so I need the hollow brick or Hollow concrete block properties but I can not fine them in material data base of wufi . I simulated it whit solid brick and Aerated clay brick( 600kg/m3) but the results almost are same and it is different whit my measurement. could you please help me :
1- The properties of hollow brick or concrete block
2-How can i calibrate the result of this layer you can fine the graphs in attachment file.
Regards
