AASHTO T 314, параграф 10.7.1:
Now demold the trimmed specimen by gently sliding the specimen and the two mold side plates
toward one edge of the bottom plate until the side plate nearest to the edge is halfway across the
edge. Pivot the overhanging side plate downward using gentle pressure and demold that side.
Replace the just released plate and now slide the specimen and the two side plates (one side
demolded but reassembled) toward the other edge and repeat the procedure given above.
Вообще, вопрос касается последнего предложения как такового: как может быть demolded, но reassembled?

См. тж. 10.7.2 для контекста:
Next, repeat the above demolding procedure, except this time remove one side plate completely
and gently mount one of the cold side plates from the cooling bath or chamber onto that side of
the specimen. Now demold the other mold side plate and mount the other cold side plate from
the cooling bath or chamber. At this point the specimen and mold assembly should look exactly
like the trimmed specimen before demolding except the two side plates are now replaced with
cold side plates that were placed in the cooling chamber or bath before the demolding process
began.
