Curing under the same conditions: At least one group (a group of 3 cube test blocks) should be retained for standard curing and curing at the same time for each sampling. For specimens of the same strength level and under the same conditions, the number to be retained should be determined according to the quantity and importance of the concrete project, ranging from 3 to 10 Group

The supervision unit shall organize the construction unit to implement the concrete structure physical inspection (rebound) and witness the implementation process; the construction unit shall formulate a special structural physical inspection plan
