Why are spacers used in concrete?

What is spacer block?
The spacer block is a framework fitted around each end of the pipe or conduit to separate it is physically from the other pipes in the bore. Multiple pipes in the bore may each have spacer blocks attached. The spacer blocks can be interlocked to form matrix through which the pipes are conduits they run.
What is spacer in P&ID?
What is a Spectacle blind and Spacer. Spectacle blind and Spacers are a pressure-retaining device used in the piping/pipeline industry to temporarily or permanently blind (shut) or isolate part of the piping or pipeline system.
What is paddle blind?
