IF MULTISCALE --> THEN MULTIDISCIPLINARY?

It's almost two years that I decide how to model the phenomenon of ASR in concrete structures. My choice is a multiscale material model based on poromechanics theory developed by Coussy, Dormieux, Ulm and further applied by Lemarchand and Charpin.
I like a lot this approach because you can bridge scales, the equations can be solved analytically and it proved to describe properly the mechanical behavior of concrete.

But today while reading the book titled "Mechanics and Physics of Porous Solid", I was asking to myself if it is indeed necessary to have a multidisciplinary approach to model this problem.
Can ASR in concrete be explained considering only mechanics? or do we need physics and chemistry too?
I don't have any answer at the moment, if you find one just let me know :)
Apparently, by crossing multiple scales you need to learn multiple disciplines!

Modeling ASR in concrete structures, it looks like finishing a puzzle. (picture from biotuesdays.com)
