Which term relates to the time after which curing compound should be applied?

• A. Vibrator Use
• B. Curing Compound Application Time
• C. FDOT Concrete Source
• D. Bridge Deck Concrete Removal

Answer: (B)

The key idea is the timing of when to seal the concrete with curing compound to keep moisture in for proper hydration. The term that matches this concept is the Curing Compound Application Time. It defines the window after finishing when the curing compound should be applied to maximize moisture retention and prevent premature drying.

Applying curing compound at the right moment is essential because it slows evaporation and helps the concrete gain strength and durability. If you apply it too soon, you might trap bleed water and interfere with surface finish; if you wait too long, the surface can dry out too quickly, increasing the risk of plastic shrinkage cracks and inadequate curing.

The other options don’t address this timing aspect: vibrator use relates to consolidation and surface finish, not when to apply curing compound; FDOT Concrete Source and Bridge Deck Concrete Removal are unrelated to curing timing.
