Where should cylinders that are going to be field cured be stored?

In a controlled laboratory environment
In or on the structure near the point of concrete deposit
In a separate curing room away from the site
In a shaded area protected from direct sunlight

The correct answer is: In or on the structure near the point of concrete deposit

Cylinders that are going to be field cured should be stored in or on the structure near the point of concrete deposit. This method allows the cured specimens to closely match the conditions that the concrete in the structure experiences, including temperature and humidity levels. By curing the cylinders in the same environmental conditions, you can ensure that the strength and durability tests performed on them will accurately reflect the performance of the actual concrete in the field. Storing cylinders in the same environment as the freshly poured concrete also minimizes the risk of discrepancies in moisture loss and temperature variations, which could affect the hydration process of the concrete. This is important for obtaining reliable test results that accurately represent the on-site conditions and performance of the concrete.
