What must be done after finishing the specimen?

• A. Mark the specimen to identify the concrete it represents; move the specimen to an initial curing location for storage.
• B. Immediately ship to the lab
• C. Leave it as is
• D. Photograph it only

Answer: (A)

After finishing a concrete specimen, the focus is on identification and proper curing. You must mark the specimen to clearly identify which concrete mix, batch, date, and specimen number it represents, ensuring you can trace the result back to the exact sample. Then move the specimen to an initial curing location where it can start curing under controlled temperature and humidity. This preserves moisture and strength development so the test results are valid.

Shipping the specimen immediately would disrupt curing and could misplace or misidentify the sample. Leaving it unmarked risks losing traceability, and photographing it alone doesn’t ensure proper curing or identification.
