With increase using of precast concrete members, ... can its damaged units reused...?
Every thing can do, only have to calculate that: worth it? Can easy do it?
Reg,

Dear László Attila Horváth .. you are right.. its maybe related to its being worthily or not..
Thanks for answering..
Dear Asad Hanif
... thanks for answering...You mention " damage is beyond repair " for aggregate.. Explain this term please..
Dear M. A. A. Al- Fatlawi ... Thanks for joining our discussion...
Absolutely. It is done all over the US. The only issue is ensuring the structural integrity of the member.
Dear Douglas D. Gransberg .. Thanks for answering...
Please explain more the meaning of " ensuring the structural integrity of the member"
Precast concrete members can be used for any construction after dismantling and re-linking.
Precast concrete members are unique in that they are individually engineered products that can be detached and relocated, facilitating future additions to buildings. When future additions occur, non-loadbearing panels on the end simply are disconnected from the framing, and new panels and framing are added on each side. With the new addition in place, the original end panels can be replaced.
When ultimately removed from service, precast concrete members may be reused in other applications. Because it comes apart with a minimum amount of energy and retains its original qualities, precast concrete is also friendly to downcycling, a process in which building materials are broken down. Concrete pieces from demolished structures, for example, can be reused to protect shorelines, and recycled concrete is frequently crushed and used as fill or road base.
Dear Husam:
Certainly. However, there must be forethought given to reuse at the time of initial design. For instance, the selection and detailing of reinforcement should consider possible conditions for reuse, otherwise external reinforcement would have to be used upon reuse. Material durability becomes an even more important issue, as a reused precast member should not have compromised material quality. Lastly, future trends in applicable building codes will affect what is acceptable, and what is not, at the time of reuse: ANy advanced information on possible building code changes should be considered.

I hope that this information helps you.

Dear Arturo E Schultz .. thanks for answering ... and for references ... I really appreciate..
It depends on design solutions. In the case of floor and wall precast panels in residential buildings, the joints of panels are made as monolithic reinforced concrete tie beams and vertical joints between precast panels. This significantly complicates the possibility of disassembling the structure. Most often it will not be profitable.
