The chemistry process may expand the volume of the concrete building and produce the local concentrated stress.
The expansion may get strong with time and change the uniform previous structure of concrete to result in the deformation, expansion and destroy of the building( M.D.A.
At the second stage, the amount of expansion materials generate great expansion stress, destroy the pore structure and expand the small cracks.

EVA due to conjugative chemical structure generates free radicals at lower radiation doses compared to LDPE [11].
This ever-increasing three-dimensional gel-like structure brought a decrease in internal chain mobility and elongation.
