What Is The Purpose Of Curing?

Why is curing important?

Curing plays an important role on strength development and durability of concrete.

Properly cured concrete has an adequate amount of moisture for continued hydration and development of strength, volume stability, resistance to freezing and thawing, and abrasion and scaling resistance.

….

Why water is required for curing of concrete?

Water Curing – is done by spraying or sprinkling water over the concrete surface to ensure that the concrete surface remains continuously moist. This prevents the moisture from the body of concrete from evaporating and contributes to the strength gain of concrete.

When concrete dries, it produces heat.

How many days curing should be done?
