Fog Curing

Definition

Fog curing is the process of storing concrete in a moist room with high humidity achieved by the atomization of fresh water, or applying atomized water directly to concrete, stucco, mortar, or plaster.

Purpose

The purpose of fog curing is to maintain optimal moisture levels in concrete and other materials during the curing process, ensuring proper hydration, strength development, and minimizing the risk of cracks.

Examples of Use

• Concrete slabs for large infrastructure projects often undergo fog curing to achieve uniform strength and durability.
• Decorative stucco finishes on buildings may use fog curing to prevent rapid drying and cracking.

Related Terms

• Curing: The process of maintaining adequate moisture, temperature, and time to allow concrete to achieve its desired properties.
• Moist Curing: Keeping concrete surfaces continuously wet by covering with wet burlap, plastic sheets, or sprinkling water.
• Steam Curing: A curing method where concrete is exposed to steam to accelerate strength gain.

Notes

Proper fog curing requires careful control of humidity and temperature. It is particularly beneficial in hot and dry climates where rapid moisture loss can occur.
