The pressure test strength value of "same condition curing test block" is an important index to reflect the solid strength of concrete structure. Refers to the specimen which is placed together with the concrete structure or member after demoulding, cured in the same temperature and humidity environment, and tested for strength when it reaches the equivalent age. Its test strength is an important basis for structural acceptance.

"Concrete structure entity strength curing test block with the same condition" (hereinafter referred to as "curing test block with the same condition") is a new regulation put forward in the new Code for Acceptance of Construction Quality of Concrete Structure Engineering (GB50204-2002). However, in our recent supervision work, it is found that some construction, supervision and construction units do not fully understand the concept of "same condition maintenance test block", and there are omissions or mistakes in construction.
