What evidence supports curing adequacy over time in final acceptance?

• A. Cure records and photos.
• B. Only batch tickets.
• C. Only cylinder results.
• D. Only weather data.

Answer: (A)

Curing adequacy over time is shown by documentation that curing was performed and maintained for the required duration. Cure records capture the daily or periodic details of how curing was applied—the method (water, curing compound, moist curing, blankets), the dates, and the duration—so you can verify that the concrete stayed in the proper moisture or temperature range for the specified period. Photos complement this by providing visual proof of the actual curing conditions on site—showing blankets in place, forms covered, or water curing being used—helps confirm that the intended curing practices were implemented across the entire surface and duration.

Relying on other data alone isn’t as solid for proving curing adequacy. Batch tickets document mix design and materials but not how the concrete was cured over time. Cylinder results indicate strength outcomes but don’t prove that curing was applied consistently throughout the curing period. Weather data shows environmental conditions, which can influence curing, but it doesn’t demonstrate that the required curing actions were actually performed.
