Curing Compound is defined as which of the following?

• A. Liquid or spray-applied materials that form a film on the concrete surface to minimize evaporation and retain moisture
• B. A dry powder mixed into the concrete to speed set
• C. A pigment added to improve color
• D. A sealant used after curing

Answer: (A)

Curing compounds are liquids applied to the surface of fresh concrete to form a protective film that minimizes water evaporation and keeps moisture in during the early curing period. This moisture retention allows cement hydration to proceed properly, leading to better strength and durability. They are used after finishing when moisture loss would otherwise occur, and they are not dry powders added to the mix (that would be an accelerator), not pigments for color, and not sealants applied after curing.
