Thus, once sample feeding becomes careless, considerable loss is caused to the project.
There are two types of concrete test blocks in the project: one is a standard maintenance test block (called standard maintenance for short); the other is the same condition curing test block. The standard-maintained test block refers to the strength of the test block after the test block is maintained under standard conditions (the temperature is 20 +/-3 ℃, and the relative humidity is more than 90%), and the test block is divided into 3 days, 7 days and 28 days in age. The maintenance field is consistent with the mix proportion trial-mix conditions, so the standard maintenance test block can only detect the difference between the strength of the concrete stirred on the site and the mix proportion theoretical value, and cannot reflect the actual strength of the concrete in the engineering structure. The curing under the same condition refers to the hardening condition (temperature and relative humidity) of the concrete test block in nature, which is completely the same as the hardening condition (natural curing, evaporation, infrared thermal curing, electric heating curing, and the like) of the concrete with the engineering structure.

Therefore, the conservation test block under the same condition is used for checking the difference between the actual strength of the engineering structural member and the structure calculation theoretical value.
The test block is an important mark for measuring the quality of the concrete member. Therefore, when the concrete member is poured, a certain amount of the same material as the concrete must be taken out to be made into a test block.
