At the end of life of building materials, disposal of the waste materials has become problems, such as environmental pollution and waste of resources.
Therefore, a concept of closed-loop material flows has been proposed, indicating the recovery of demolished materials so that materials collected at the deconstruction phase could be inked back into material flows in the same or different condition after recovery [5].
In this analysis, the amount of materials only for main structure use is considered and materials for inner decoration are not taken into account.

Introduction The releasing of elastic energy which produced by the micro cracks initiation, development, and ultimate fracture of rock-like materials, causes the rock-like materials have acoustic emission (AE) phenomenon.
On this basis the cataclysms of rock-like materials also can be forecasted [1,2].
As one of man-made materials, cemented backfill contains a large number of micro holes and micro cracks in its internal.
