Curing blankets are used for what purpose?

• A. To maintain temperature during curing, especially in cold weather, helping to prevent freezing and ensuring continued hydration
• B. To decorate the surface
• C. To shorten curing time by evaporating moisture
• D. To strengthen the steel reinforcement

Answer: (A)

Curing blankets are used to maintain the temperature of the concrete during curing, especially in cold weather, to prevent freezing and ensure continued hydration. Concrete needs warmth to allow the cement to hydrate properly; if it freezes or dries out, strength development can be compromised. The blanket insulates the surface, slows heat loss, and reduces moisture evaporation, keeping the concrete moist and at a suitable temperature for a solid cure. They’re not for decoration, they don’t speed curing by evaporating moisture, and they don’t directly affect the strength of steel reinforcement.
