Upon completion of initial curing, the test specimens may be left in their molds and sealed in plastic bags. true or false?

• A. False
• B. True
• C. Cannot determine
• D. N/A

Answer: (A)

After the initial curing period, test specimens should be removed from their molds and placed in a proper moisture-curing environment. Leaving them in the molds and sealing them in plastic bags keeps the specimens restrained and can cause uneven moisture distribution and altered end conditions, which affects the accuracy of the strength test. Demolding promptly and curing in controlled moisture (such as water, moist air, or sealed containers) ensures consistent dimensions and surface conditions for testing. So this statement is false.
