Seal curing refers to which method?

• A. Using curing compounds that form a moisture-retaining film
• B. Immersing the concrete in water
• C. Heating the surface with steam
• D. Using paints to color the surface

Answer: (A)

The method being tested is about keeping moisture in the concrete by forming a protective surface film. Seal curing uses a film-forming curing compound applied to the surface that dries into a continuous barrier, reducing water evaporation from the concrete as it hydrates. By locking in moisture, the hydration process continues effectively, improving strength development and minimizing shrinkage cracking. This is different from immersing the concrete in water, which directly adds moisture by submerging the entire surface (moist curing); and from heating with steam, which relies on heat and humidity to speed up curing (steam curing). Using paints to color the surface doesn’t provide the moisture-retaining barrier needed for proper curing and is not considered a curing method.
